    • Field Detail

      • INSTANCE

        static final Kernel32 INSTANCE
        The instance.

      • LOAD_LIBRARY_AS_DATAFILE

        static final int LOAD_LIBRARY_AS_DATAFILE
        LOAD_LIBRARY_AS_DATAFILE
        0x00000002
        If this value is used, the system maps the file into the calling process's virtual address space as if it were a data file.
        Nothing is done to execute or prepare to execute the mapped file.
        Therefore, you cannot call functions like GetModuleFileName , GetModuleHandle or GetProcAddress with this DLL. Using this value causes writes to read-only memory to raise an access violation.
        Use this flag when you want to load a DLL only to extract messages or resources from it.
        This value can be used with LOAD_LIBRARY_AS_IMAGE_RESOURCE. For more information, see Remarks.

      • ReadFile

        boolean ReadFile(WinNT.HANDLE hFile,
                 byte[] lpBuffer,
                 int nNumberOfBytesToRead,
                 IntByReference lpNumberOfBytesRead,
                 WinBase.OVERLAPPED lpOverlapped)
        Reads data from the specified file or input/output (I/O) device. Reads occur at the position specified by the file pointer if supported by the device. This function is designed for both synchronous and asynchronous operations. For a similar function designed solely for asynchronous operation, see ReadFileEx
        Parameters:
        hFile - A handle to the device (for example, a file, file stream, physical disk, volume, console buffer, tape drive, socket, communications resource, mailslot, or pipe).
        lpBuffer - A pointer to the buffer that receives the data read from a file or device.
        nNumberOfBytesToRead - The maximum number of bytes to be read.
        lpNumberOfBytesRead - A pointer to the variable that receives the number of bytes read when using a synchronous hFile parameter
        lpOverlapped - A pointer to an OVERLAPPED structure is required if the hFile parameter was opened with FILE_FLAG_OVERLAPPED, otherwise it can be NULL.
        Returns:
        If the function succeeds, the return value is nonzero (TRUE). If the function fails, or is completing asynchronously, the return value is zero (FALSE). To get extended error information, call the GetLastError function. Note The GetLastError code ERROR_IO_PENDING is not a failure; it designates the read operation is pending completion asynchronously. For more information, see Remarks.

        The FormatMessage function formats a message string. The function requires a message definition as input. The message definition can come from a buffer passed into the function. It can come from a message table resource in an already-loaded module. Or the caller can ask the function to search the system's message table resource(s) for the message definition. The function finds the message definition in a message table resource based on a message identifier and a language identifier. The function copies the formatted message text to an output buffer, processing any embedded insert sequences if requested.
        Parameters:
        dwFlags - Formatting options, and how to interpret the lpSource parameter. The low-order byte of dwFlags specifies how the function handles line breaks in the output buffer. The low-order byte can also specify the maximum width of a formatted output line.

        This version of the function assumes FORMAT_MESSAGE_ALLOCATE_BUFFER is set.

        lpSource - Location of the message definition.
        dwMessageId - Message identifier for the requested message.
        dwLanguageId - Language identifier for the requested message.
        lpBuffer - Pointer to a pointer that receives the allocated buffer in which the null-terminated string that specifies the formatted message is written.
        nSize - This parameter specifies the minimum number of TCHARs to allocate for an output buffer.
        va_list - Pointer to an array of values that are used as insert values in the formatted message.
        Returns:
        If the function succeeds, the return value is the number of TCHARs stored in the output buffer, excluding the terminating null character. If the function fails, the return value is zero. To get extended error information, call GetLastError.

        dwCreationDisposition - An action to take on files that exist and do not exist.
        dwFlagsAndAttributes - The file attributes and flags.
        hTemplateFile - Handle to a template file with the GENERIC_READ access right. The template file supplies file attributes and extended attributes for the file that is being created. This parameter can be NULL.
        Returns:
        If the function succeeds, the return value is an open handle to a specified file. If a specified file exists before the function call and dwCreationDisposition is CREATE_ALWAYS or OPEN_ALWAYS, a call to GetLastError returns ERROR_ALREADY_EXISTS, even when the function succeeds. If a file does not exist before the call, GetLastError returns 0 (zero). If the function fails, the return value is INVALID_HANDLE_VALUE. To get extended error information, call GetLastError.

        Moves an existing file or directory, including its children, with various move options.
        Parameters:
        lpExistingFileName - The current name of the file or directory on the local computer. If dwFlags specifies MOVEFILE_DELAY_UNTIL_REBOOT, the file cannot exist on a remote share, because delayed operations are performed before the network is available. The name is limited to MAX_PATH characters. To extend this limit to 32,767 wide characters, prepend "\\?\" to the path. For more information, see Naming a File Windows 2000: If you prepend the file name with "\\?\", you cannot also specify the MOVEFILE_DELAY_UNTIL_REBOOT flag for dwFlags.
        lpNewFileName - The new name of the file or directory on the local computer. When moving a file, the destination can be on a different file system or volume. If the destination is on another drive, you must set the MOVEFILE_COPY_ALLOWED flag in dwFlags. When moving a directory, the destination must be on the same drive. If dwFlags specifies MOVEFILE_DELAY_UNTIL_REBOOT and lpNewFileName is NULL, MoveFileEx registers the lpExistingFileName file to be deleted when the system restarts. If lpExistingFileName refers to a directory, the system removes the directory at restart only if the directory is empty.
        dwFlags - This parameter can be one or more of the following values.
        Returns:
        true, if successful If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. To get extended error information, call GetLastError.

        Parameters:
        lpPathName - Pointer to a null-terminated string that specifies the path of the directory to be created.
        lpSecurityAttributes - Pointer to a SECURITY_ATTRIBUTES structure. The lpSecurityDescriptor member of the structure specifies a security descriptor for the new directory. If lpSecurityAttributes is NULL, the directory gets a default security descriptor.
        Returns:
        If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. To get extended error information, call GetLastError.

        Returns:
        If the function succeeds, the return value is the handle to an I/O completion port: If the ExistingCompletionPort parameter was NULL, the return value is a new handle. If the ExistingCompletionPort parameter was a valid I/O completion port handle, the return value is that same handle. If the FileHandle parameter was a valid handle, that file handle is now associated with the returned I/O completion port. If the function fails, the return value is NULL. To get extended error information, call the GetLastError function.

        dwMilliseconds - The time-out interval, in milliseconds. If a nonzero value is specified, the function waits until the object is signaled or the interval elapses. If dwMilliseconds is zero, the function does not enter a wait state if the object is not signaled; it always returns immediately. If dwMilliseconds is INFINITE, the function will return only when the object is signaled.
        Returns:
        If the function succeeds, the return value indicates the event that caused the function to return.

      • WaitForMultipleObjects

        int WaitForMultipleObjects(int nCount,
                           WinNT.HANDLE[] hHandle,
                           boolean bWaitAll,
                           int dwMilliseconds)
        Waits until one or all of the specified objects are in the signaled state or the time-out interval elapses. To enter an alertable wait state, use the WaitForMultipleObjectsEx function.
        Parameters:
        nCount - The number of object handles in the array pointed to by lpHandles. The maximum number of object handles is MAXIMUM_WAIT_OBJECTS.
        hHandle - An array of object handles. For a list of the object types whose handles can be specified, see the following Remarks section. The array can contain handles to objects of different types. It may not contain multiple copies of the same handle. If one of these handles is closed while the wait is still pending, the function's behavior is undefined. The handles must have the SYNCHRONIZE access right. For more information, see Standard Access Rights.
        bWaitAll - If this parameter is TRUE, the function returns when the state of all objects in the lpHandles array is signaled. If FALSE, the function returns when the state of any one of the objects is set to signaled. In the latter case, the return value indicates the object whose state caused the function to return.
        dwMilliseconds - The time-out interval, in milliseconds. If a nonzero value is specified, the function waits until the specified objects are signaled or the interval elapses. If dwMilliseconds is zero, the function does not enter a wait state if the specified objects are not signaled; it always returns immediately. If dwMilliseconds is INFINITE, the function will return only when the specified objects are signaled.
        Returns:
        If the function succeeds, the return value indicates the event that caused the function to return.

        length - The size of the buffer that is pointed to by the lpBuffer parameter, in bytes.
        watchSubtree - If this parameter is TRUE, the function monitors the directory tree rooted at the specified directory. If this parameter is FALSE, the function monitors only the directory specified by the hDirectory parameter.
        notifyFilter - The filter criteria that the function checks to determine if the wait operation has completed.
        bytesReturned - For synchronous calls, this parameter receives the number of bytes transferred into the lpBuffer parameter. For asynchronous calls, this parameter is undefined. You must use an asynchronous notification technique to retrieve the number of bytes transferred.
        overlapped - A pointer to an OVERLAPPED structure that supplies data to be used during asynchronous operation. Otherwise, this value is NULL. The Offset and OffsetHigh members of this structure are not used.
        completionRoutine - A pointer to a completion routine to be called when the operation has been completed or canceled and the calling thread is in an alertable wait state.
        Returns:
        If the function succeeds, the return value is nonzero. For synchronous calls, this means that the operation succeeded. For asynchronous calls, this indicates that the operation was successfully queued. If the function fails, the return value is zero. To get extended error information, call GetLastError. If the network redirector or the target file system does not support this operation, the function fails with ERROR_INVALID_FUNCTION.

      • CreateProcessW

        boolean CreateProcessW(String lpApplicationName,
                       char[] lpCommandLine,
                       WinBase.SECURITY_ATTRIBUTES lpProcessAttributes,
                       WinBase.SECURITY_ATTRIBUTES lpThreadAttributes,
                       boolean bInheritHandles,
                       WinDef.DWORD dwCreationFlags,
                       Pointer lpEnvironment,
                       String lpCurrentDirectory,
                       WinBase.STARTUPINFO lpStartupInfo,
                       WinBase.PROCESS_INFORMATION lpProcessInformation)
        Creates a new process and its primary thread. The new process runs in the security context of the calling process.
        Parameters:
        lpApplicationName - The name of the module to be executed.
        lpCommandLine - The command line to be executed. The maximum length of this string is 32,768 characters, including the Unicode terminating null character. If lpApplicationName is NULL, the module name portion of lpCommandLine is limited to MAX_PATH characters.

        The Unicode version of this function, CreateProcessW(java.lang.String, char[], com.sun.jna.platform.win32.WinBase.SECURITY_ATTRIBUTES, com.sun.jna.platform.win32.WinBase.SECURITY_ATTRIBUTES, boolean, com.sun.jna.platform.win32.WinDef.DWORD, com.sun.jna.Pointer, java.lang.String, com.sun.jna.platform.win32.WinBase.STARTUPINFO, com.sun.jna.platform.win32.WinBase.PROCESS_INFORMATION), can modify the contents of this string. Therefore, this parameter cannot be a pointer to read-only memory (such as a const variable or a literal string). If this parameter is a constant string, the function may cause an access violation.

        The lpCommandLine parameter can be NULL. In that case, the function uses the string pointed to by lpApplicationName as the command line.

        If both lpApplicationName and lpCommandLine are non-NULL, the null-terminated string pointed to by lpApplicationName specifies the module to execute, and the null-terminated string pointed to by lpCommandLine specifies the command line. The new process can use GetCommandLine to retrieve the entire command line. Console processes written in C can use the argc and argv arguments to parse the command line. Because argv[0] is the module name, C programmers generally repeat the module name as the first token in the command line.

        If lpApplicationName is NULL, the first white space-delimited token of the command line specifies the module name. If you are using a long file name that contains a space, use quoted strings to indicate where the file name ends and the arguments begin (see the explanation for the lpApplicationName parameter). If the file name does not contain an extension, .exe is appended. Therefore, if the file name extension is .com, this parameter must include the .com extension. If the file name ends in a period (.) with no extension, or if the file name contains a path, .exe is not appended. If the file name does not contain a directory path, the system searches for the executable file in the following sequence:
        • The directory from which the application loaded.
        • The current directory for the parent process.
        • The 32-bit Windows system directory. Use the GetSystemDirectory function to get the path of this directory.
        • The 16-bit Windows system directory. There is no function that obtains the path of this directory, but it is searched. The name of this directory is System.
        • The Windows directory. Use the GetWindowsDirectory function to get the path of this directory.
        • The directories that are listed in the PATH environment variable. Note that this function does not search the per-application path specified by the App Paths registry key. To include this per-application path in the search sequence, use the ShellExecute function.
        The system adds a terminating null character to the command-line string to separate the file name from the arguments. This divides the original string into two strings for internal processing.
        lpProcessAttributes - A pointer to a SECURITY_ATTRIBUTES structure that determines whether the returned handle to the new process object can be inherited by child processes. If lpProcessAttributes is NULL, the handle cannot be inherited.
        lpThreadAttributes - A pointer to a SECURITY_ATTRIBUTES structure that determines whether the returned handle to the new thread object can be inherited by child processes. If lpThreadAttributes is NULL, the handle cannot be inherited.
        bInheritHandles - If this parameter TRUE, each inheritable handle in the calling process is inherited by the new process. If the parameter is FALSE, the handles are not inherited. Note that inherited handles have the same value and access rights as the original handles.
        dwCreationFlags - The flags that control the priority class and the creation of the process.
        lpEnvironment - A pointer to the environment block for the new process. If this parameter is NULL, the new process uses the environment of the calling process.
        lpCurrentDirectory - The full path to the current directory for the process.
        lpStartupInfo - A pointer to a STARTUPINFO or STARTUPINFOEX structure.
        lpProcessInformation - A pointer to a PROCESS_INFORMATION structure that receives identification information about the new process.
        Returns:
        If the function succeeds, the return value is nonzero.

        Returns:
        FILE_TYPE_UNKNOWN if the function fails, or if the type is unknown. You can distinguish between a "valid" return of FILE_TYPE_UNKNOWN and its return due to a calling error (for example, passing an invalid handle to GetFileType) by calling GetLastError. If the function worked properly and FILE_TYPE_UNKNOWN was returned, a call to GetLastError will return NO_ERROR.

      • DeviceIoControl

        boolean DeviceIoControl(WinNT.HANDLE hDevice,
                        int dwIoControlCode,
                        Pointer lpInBuffer,
                        int nInBufferSize,
                        Pointer lpOutBuffer,
                        int nOutBufferSize,
                        IntByReference lpBytesReturned,
                        Pointer lpOverlapped)
        Sends a control code directly to a specified device driver, causing the corresponding device to perform the corresponding operation.
        Parameters:
        hDevice - A handle to the device on which the operation is to be performed. The device is typically a volume, directory, file, or stream. To retrieve a device handle, use the CreateFile function. For more information, see Remarks.
        dwIoControlCode - The control code for the operation. This value identifies the specific operation to be performed and the type of device on which to perform it. For a list of the control codes, see Remarks. The documentation for each control code provides usage details for the lpInBuffer, nInBufferSize, lpOutBuffer, and nOutBufferSize parameters.
        lpInBuffer - A pointer to the input buffer that contains the data required to perform the operation. The format of this data depends on the value of the dwIoControlCode parameter. This parameter can be NULL if dwIoControlCode specifies an operation that does not require input data.
        nInBufferSize - The size of the input buffer, in bytes.
        lpOutBuffer - A pointer to the output buffer that is to receive the data returned by the operation. The format of this data depends on the value of the dwIoControlCode parameter. This parameter can be NULL if dwIoControlCode specifies an operation that does not return data.
        nOutBufferSize - The size of the output buffer, in bytes.
        lpBytesReturned - A pointer to a variable that receives the size of the data stored in the output buffer, in bytes. If the output buffer is too small to receive any data, the call fails, GetLastError returns ERROR_INSUFFICIENT_BUFFER, and lpBytesReturned is zero. If the output buffer is too small to hold all of the data but can hold some entries, some drivers will return as much data as fits. In this case, the call fails, GetLastError returns ERROR_MORE_DATA, and lpBytesReturned indicates the amount of data received. Your application should call DeviceIoControl again with the same operation, specifying a new starting point. If lpOverlapped is NULL, lpBytesReturned cannot be NULL. Even when an operation returns no output data and lpOutBuffer is NULL, DeviceIoControl makes use of lpBytesReturned. After such an operation, the value of lpBytesReturned is meaningless. If lpOverlapped is not NULL, lpBytesReturned can be NULL. If this parameter is not NULL and the operation returns data, lpBytesReturned is meaningless until the overlapped operation has completed. To retrieve the number of bytes returned, call GetOverlappedResult. If hDevice is associated with an I/O completion port, you can retrieve the number of bytes returned by calling GetQueuedCompletionStatus.
        lpOverlapped - A pointer to an OVERLAPPED structure. If hDevice was opened without specifying FILE_FLAG_OVERLAPPED, lpOverlapped is ignored. If hDevice was opened with the FILE_FLAG_OVERLAPPED flag, the operation is performed as an overlapped (asynchronous) operation. In this case, lpOverlapped must point to a valid OVERLAPPED structure that contains a handle to an event object. Otherwise, the function fails in unpredictable ways. For overlapped operations, DeviceIoControl returns immediately, and the event object is signaled when the operation has been completed. Otherwise, the function does not return until the operation has been completed or an error occurs.
        Returns:
        If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. To get extended error information, call GetLastError.

      • CreateToolhelp32Snapshot

                                      WinDef.DWORD th32ProcessID)
        Takes a snapshot of the specified processes, as well as the heaps, modules, and threads used by these processes.
        Parameters:
        dwFlags - The portions of the system to be included in the snapshot.
        th32ProcessID - The process identifier of the process to be included in the snapshot. This parameter can be zero to indicate the current process. This parameter is used when the TH32CS_SNAPHEAPLIST, TH32CS_SNAPMODULE, TH32CS_SNAPMODULE32, or TH32CS_SNAPALL value is specified. Otherwise, it is ignored and all processes are included in the snapshot. If the specified process is the Idle process or one of the CSRSS processes, this function fails and the last error code is ERROR_ACCESS_DENIED because their access restrictions prevent user-level code from opening them. If the specified process is a 64-bit process and the caller is a 32-bit process, this function fails and the last error code is ERROR_PARTIAL_COPY (299).
        Returns:
        If the function succeeds, it returns an open handle to the specified snapshot. If the function fails, it returns INVALID_HANDLE_VALUE. To get extended error information, call GetLastError. Possible error codes include ERROR_BAD_LENGTH.

        lpReturnedString - A pointer to the buffer that receives the retrieved string.
        nSize - The size of the buffer pointed to by the lpReturnedString parameter, in characters.
        lpFileName - The name of the initialization file. If this parameter does not contain a full path to the file, the system searches for the file in the Windows directory.
        Returns:
        The return value is the number of characters copied to the buffer, not including the terminating null character.

        If neither lpAppName nor lpKeyName is null and the supplied destination buffer is too small to hold the requested string, the string is truncated and followed by a null character, and the return value is equal to nSize minus one.

        If either lpAppName or lpKeyName is null and the supplied destination buffer is too small to hold all the strings, the last string is truncated and followed by two null characters. In this case, the return value is equal to nSize minus two.

        In the event the initialization file specified by lpFileName is not found, or contains invalid values, this function will set errorno with a value of '0x2' (File Not Found). To retrieve extended error information, call GetLastError().

        Retrieves information about MS-DOS device names
        Parameters:
        lpDeviceName - An MS-DOS device name string specifying the target of the query. The device name cannot have a trailing backslash; for example, use "C:", not "C:\". This parameter can be NULL. In that case, the function will store a list of all existing MS-DOS device names into the buffer.
        lpTargetPath - A buffer that will receive the result of the query. The function fills this buffer with one or more null-terminated strings. The final null-terminated string is followed by an additional NULL. If device name is non-NULL, the function retrieves information about the particular MS-DOS device. The first null-terminated string stored into the buffer is the current mapping for the device. The other null-terminated strings represent undeleted prior mappings for the device. Each null-terminated string stored into the buffer is the name of an existing MS-DOS device, for example, \Device\HarddiskVolume1 or \Device\Floppy0.
        ucchMax - The maximum number of characters that can be stored into the buffer
        Returns:
        If the function succeeds, the return value is the number of characters stored into the buffer, otherwise zero. Use GetLastError() to get extended error information. If the buffer is too small, the function fails and the last error code is ERROR_INSUFFICIENT_BUFFER.

        WinNT.HANDLE FindFirstFile(String lpFileName,
                           Pointer lpFindFileData)
        Searches a directory for a file or subdirectory with a name that matches a specific name (or partial name if wildcards are used). To specify additional attributes to use in a search, use the FindFirstFileEx function.
        Parameters:
        lpFileName - The directory or path, and the file name. The file name can include wildcard characters, for example, an asterisk (*) or a question mark (?). This parameter should not be NULL, an invalid string (for example, an empty string or a string that is missing the terminating null character), or end in a trailing backslash (\). If the string ends with a wildcard, period, or directory name, the user must have access to the root and all subdirectories on the path. In the ANSI version of this function, the name is limited to MAX_PATH characters. To extend this limit to approximately 32,000 wide characters, call the Unicode version of the function (FindFirstFileExW), and prepend "\\?\" to the path. For more information, see Naming a File. Tip Starting in Windows 10, version 1607, for the unicode version of this function (FindFirstFileExW), you can opt-in to remove the MAX_PATH character limitation without prepending "\\?\". See the "Maximum Path Limitation" section of Naming Files, Paths, and Namespaces for details.
        lpFindFileData - A pointer to the buffer that receives the file data. The pointer type is determined by the level of information that is specified in the fInfoLevelId parameter.
        Returns:
        If the function succeeds, the return value is a search handle used in a subsequent call to FindNextFile or FindClose, and the lpFindFileData parameter contains information about the first file or directory found. If the function fails or fails to locate files from the search string in the lpFileName parameter, the return value is INVALID_HANDLE_VALUE and the contents of lpFindFileData are indeterminate. To get extended error information, call the GetLastError function. If the function fails because no matching files can be found, the GetLastError function returns ERROR_FILE_NOT_FOUND.

        lpszVolumeMountPoint - A buffer that receives the name of the first mounted folder that is found.
        cchBufferLength - The length of the buffer that receives the path to the mounted folder
        Returns:
        If succeeds, a search handle used in a subsequent call to the FindNextVolumeMountPoint and FindVolumeMountPointClose functions. Otherwise, the return value is the WinBase.INVALID_HANDLE_VALUE. To get extended error information, call GetLastError().

      • LoadLibraryEx

        WinDef.HMODULE LoadLibraryEx(String lpFileName,
                             WinNT.HANDLE hFile,
                             int flags)
        Loads the specified module into the address space of the calling process. The specified module may cause other modules to be loaded. 
         
 HMODULE WINAPI LoadLibraryEx(
   _In_       LPCTSTR lpFileName,
   _Reserved_ HANDLE  hFile,
   _In_       DWORD   dwFlags
 );
        Parameters:
        lpFileName - A string that specifies the file name of the module to load. This name is not related to the name stored in a library module itself, as specified by the LIBRARY keyword in the module-definition (.def) file.
        The module can be a library module (a .dll file) or an executable module (an .exe file). If the specified module is an executable module, static imports are not loaded; instead, the module is loaded as if DONT_RESOLVE_DLL_REFERENCES was specified. See the dwFlags parameter for more information.
        If the string specifies a module name without a path and the file name extension is omitted, the function appends the default library extension .dll to the module name. To prevent the function from appending .dll to the module name, include a trailing point character (.) in the module name string.
        If the string specifies a fully qualified path, the function searches only that path for the module. When specifying a path, be sure to use backslashes (\), not forward slashes (/). For more information about paths, see "Naming Files, Paths, and Namespaces" on MSDN.
        If the string specifies a module name without a path and more than one loaded module has the same base name and extension, the function returns a handle to the module that was loaded first.
        If the string specifies a module name without a path and a module of the same name is not already loaded, or if the string specifies a module name with a relative path, the function searches for the specified module. The function also searches for modules if loading the specified module causes the system to load other associated modules (that is, if the module has dependencies). The directories that are searched and the order in which they are searched depend on the specified path and the dwFlags parameter. For more information, see Remarks.
        If the function cannot find the module or one of its dependencies, the function fails.
        hFile - This parameter is reserved for future use. It must be NULL.
        flags - The action to be taken when loading the module.
        If no flags are specified, the behavior of this function is identical to that of the LoadLibrary function.
        This parameter can be one of the following values.

        DONT_RESOLVE_DLL_REFERENCES: 0x00000001
        If this value is used, and the executable module is a DLL, the system does not call DllMain for process and thread initialization and termination. Also, the system does not load additional executable modules that are referenced by the specified module.
        Do not use this value; it is provided only for backward compatibility. If you are planning to access only data or resources in the DLL, use LOAD_LIBRARY_AS_DATAFILE_EXCLUSIVE or LOAD_LIBRARY_AS_IMAGE_RESOURCE or both. Otherwise, load the library as a DLL or executable module using the LoadLibrary function.

        LOAD_IGNORE_CODE_AUTHZ_LEVEL: 0x00000010
        If this value is used, the system does not check AppLocker rules or apply Software Restriction Policies for the DLL. AppLocker was introduced in Windows 7 and Windows Server 2008 R2. This action applies only to the DLL being loaded and not to its dependencies. This value is recommended for use in setup programs that must run extracted DLLs during installation.
        Windows Server 2008 R2 and Windows 7: On systems with KB2532445 installed, the caller must be running as "LocalSystem" or "TrustedInstaller"; otherwise the system ignores this flag.

        LOAD_LIBRARY_AS_DATAFILE: 0x00000002
        If this value is used, the system maps the file into the calling process's virtual address space as if it were a data file. Nothing is done to execute or prepare to execute the mapped file. Therefore, you cannot call functions like GetModuleFileName, GetModuleHandle or GetProcAddress with this DLL. Using this value causes writes to read-only memory to raise an access violation. Use this flag when you want to load a DLL only to extract messages or resources from it.
        This value can be used with LOAD_LIBRARY_AS_IMAGE_RESOURCE. For more information, see Remarks

        LOAD_LIBRARY_AS_DATAFILE_EXCLUSIVE: 0x00000040
        Similar to LOAD_LIBRARY_AS_DATAFILE, except that the DLL file is opened with exclusive write access for the calling process. Other processes cannot open the DLL file for write access while it is in use. However, the DLL can still be opened by other processes.
        This value can be used with LOAD_LIBRARY_AS_IMAGE_RESOURCE. This value is not supported until Windows Vista.

        LOAD_LIBRARY_AS_IMAGE_RESOURCE: 0x00000020
        If this value is used, the system maps the file into the process's virtual address space as an image file. However, the loader does not load the static imports or perform the other usual initialization steps. Use this flag when you want to load a DLL only to extract messages or resources from it.
        Unless the application depends on the file having the in-memory layout of an image, this value should be used with either LOAD_LIBRARY_AS_DATAFILE_EXCLUSIVE or LOAD_LIBRARY_AS_DATAFILE. This value is not supported until Windows Vista.

        LOAD_LIBRARY_SEARCH_APPLICATION_DIR: 0x00000200
        If this value is used, the application's installation directory is searched for the DLL and its dependencies. Directories in the standard search path are not searched. This value cannot be combined with LOAD_WITH_ALTERED_SEARCH_PATH.
        Windows 7, Windows Server 2008 R2, Windows Vista, and Windows Server 2008: This value requires KB2533623 to be installed.

        LOAD_LIBRARY_SEARCH_DEFAULT_DIRS: 0x00001000
        This value is a combination of LOAD_LIBRARY_SEARCH_APPLICATION_DIR, LOAD_LIBRARY_SEARCH_SYSTEM32, and LOAD_LIBRARY_SEARCH_USER_DIRS. Directories in the standard search path are not searched. This value cannot be combined with LOAD_WITH_ALTERED_SEARCH_PATH.
        This value represents the recommended maximum number of directories an application should include in its DLL search path.
        Windows 7, Windows Server 2008 R2, Windows Vista, and Windows Server 2008: This value requires KB2533623 to be installed.

        LOAD_LIBRARY_SEARCH_DLL_LOAD_DIR: 0x00000100
        If this value is used, the directory that contains the DLL is temporarily added to the beginning of the list of directories that are searched for the DLL's dependencies. Directories in the standard search path are not searched.
        The lpFileName parameter must specify a fully qualified path. This value cannot be combined with LOAD_WITH_ALTERED_SEARCH_PATH.
        For example, if Lib2.dll is a dependency of C:\Dir1\Lib1.dll, loading Lib1.dll with this value causes the system to search for Lib2.dll only in C:\Dir1. To search for Lib2.dll in C:\Dir1 and all of the directories in the DLL search path, combine this value with LOAD_LIBRARY_DEFAULT_DIRS.
        Windows 7, Windows Server 2008 R2, Windows Vista, and Windows Server 2008: This value requires KB2533623 to be installed.

        LOAD_LIBRARY_SEARCH_SYSTEM32: 0x00000800
        If this value is used, %windows%\system32 is searched for the DLL and its dependencies. Directories in the standard search path are not searched. This value cannot be combined with LOAD_WITH_ALTERED_SEARCH_PATH.
        Windows 7, Windows Server 2008 R2, Windows Vista, and Windows Server 2008: This value requires KB2533623 to be installed.

        LOAD_LIBRARY_SEARCH_USER_DIRS: 0x00000400
        If this value is used, directories added using the AddDllDirectory or the SetDllDirectory function are searched for the DLL and its dependencies. If more than one directory has been added, the order in which the directories are searched is unspecified. Directories in the standard search path are not searched. This value cannot be combined with LOAD_WITH_ALTERED_SEARCH_PATH.
        Windows 7, Windows Server 2008 R2, Windows Vista, and Windows Server 2008: This value requires KB2533623 to be installed.

        LOAD_WITH_ALTERED_SEARCH_PATH: 0x00000008
        If this value is used and lpFileName specifies an absolute path, the system uses the alternate file search strategy discussed in the Remarks section to find associated executable modules that the specified module causes to be loaded. If this value is used and lpFileName specifies a relative path, the behavior is undefined.
        If this value is not used, or if lpFileName does not specify a path, the system uses the standard search strategy discussed in the Remarks section to find associated executable modules that the specified module causes to be loaded.
        This value cannot be combined with any LOAD_LIBRARY_SEARCH flag.
        Returns:
        If the function succeeds, the return value is a handle to the loaded module.
        If the function fails, the return value is NULL. To get extended error information, call GetLastError.

      • FindResource

        WinDef.HRSRC FindResource(WinDef.HMODULE hModule,
                          Pointer name,
                          Pointer type)
        Determines the location of a resource with the specified type and name in the specified module.
        To specify a language, use the FindResourceEx function.
        Parameters:
        hModule - A handle to the module whose portable executable file or an accompanying MUI file contains the resource.
        If this parameter is NULL, the function searches the module used to create the current process.
        name - The name of the resource.
        Alternately, rather than a pointer, this parameter can be MAKEINTRESOURCE(ID), where ID is the integer identifier of the resource.
        For more information, see the Remarks section below.
        type - The resource type.
        Alternately, rather than a pointer, this parameter can be MAKEINTRESOURCE(ID), where ID is the integer identifier of the given resource type.
        For standard resource types, see Resource Types. For more information, see the Remarks section below.
        Returns:
        If the function succeeds, the return value is a handle to the specified resource's information block.
        To obtain a handle to the resource, pass this handle to the LoadResource function.
        If the function fails, the return value is NULL.
        To get extended error information, call GetLastError.

      • LoadResource

        WinNT.HANDLE LoadResource(WinDef.HMODULE hModule,
                          WinDef.HRSRC hResource)
        Retrieves a handle that can be used to obtain a pointer to the first byte of the specified resource in memory.
        Parameters:
        hModule - A handle to the module whose executable file contains the resource.
        If hModule is NULL, the system loads the resource from the module that was used to create the current process.
        hResource - A handle to the resource to be loaded.
        This handle is returned by the FindResource or FindResourceEx function.
        Returns:
        If the function succeeds, the return value is a handle to the data associated with the resource.
        If the function fails, the return value is NULL.
        To get extended error information, call GetLastError.

      • LockResource

        Pointer LockResource(WinNT.HANDLE hResource)
        Retrieves a pointer to the specified resource in memory.
        Parameters:
        hResource - A handle to the resource to be accessed.
        The LoadResource function returns this handle.
        Note that this parameter is listed as an HGLOBAL variable only for backward compatibility.
        Do not pass any value as a parameter other than a successful return value from the LoadResource function.
        Returns:
        If the loaded resource is available, the return value is a pointer to the first byte of the resource; otherwise, it is NULL.

      • SizeofResource

        int SizeofResource(WinDef.HMODULE hModule,
                   WinNT.HANDLE hResource)
        Parameters:
        hModule - A handle to the module whose executable file contains the resource.
        hResource - A handle to the resource. This handle must be created by using the FindResource or FindResourceEx function.
        Returns:
        If the function succeeds, the return value is the number of bytes in the resource.
        If the function fails, the return value is zero. To get extended error information, call GetLastError.

      • FreeLibrary

        boolean FreeLibrary(WinDef.HMODULE module)
        Frees the loaded dynamic-link library (DLL) module and, if necessary, decrements its reference count. When the reference count reaches zero, the module is unloaded from the address space of the calling process and the handle is no longer valid.
        Parameters:
        module - A handle to the loaded library module. The LoadLibrary, LoadLibraryEx, GetModuleHandle, or GetModuleHandleEx function returns this handle.
        Returns:
        If the function succeeds, the return value is nonzero. If the function fails, the return value is zero. To get extended error information, call the GetLastError function.

      • EnumResourceTypes

        boolean EnumResourceTypes(WinDef.HMODULE hModule,
                          WinBase.EnumResTypeProc proc,
                          Pointer lParam)
        Enumerates resource types within a binary module.
        Starting with Windows Vista, this is typically a language-neutral Portable Executable (LN file), and the enumeration also includes resources from one of the corresponding language-specific resource files (.mui files)-if one exists-that contain localizable language resources. It is also possible to use hModule to specify a .mui file, in which case only that file is searched for resource types.
        Alternately, applications can call EnumResourceTypesEx, which provides more precise control over which resource files to enumerate.
        Parameters:
        hModule - A handle to a module to be searched.
        This handle must be obtained through LoadLibrary or LoadLibraryEx.
        See Remarks for more information. If this parameter is NULL, that is equivalent to passing in a handle to the module used to create the current process.
        proc - A pointer to the callback function to be called for each enumerated resource type.
        For more information, see the EnumResTypeProc function.
        lParam - An application-defined value passed to the callback function.
        Returns:
        Returns TRUE if successful; otherwise, FALSE. To get extended error information, call GetLastError.

      • EnumResourceNames

        boolean EnumResourceNames(WinDef.HMODULE hModule,
                          Pointer type,
                          WinBase.EnumResNameProc proc,
                          Pointer lParam)
        Enumerates resources of a specified type within a binary module.
        For Windows Vista and later, this is typically a language-neutral Portable Executable (LN file), and the enumeration will also include resources from the corresponding language-specific resource files (.mui files) that contain localizable language resources.
        It is also possible for hModule to specify an .mui file, in which case only that file is searched for resources.
        Parameters:
        hModule - A handle to a module to be searched.
        Starting with Windows Vista, if this is an LN file, then appropriate .mui files (if any exist) are included in the search.
        If this parameter is NULL, that is equivalent to passing in a handle to the module used to create the current process.
        type - The type of the resource for which the name is being enumerated.
        Alternately, rather than a pointer, this parameter can be MAKEINTRESOURCE(ID), where ID is an integer value representing a predefined resource type.
        For a list of predefined resource types, see Resource Types. For more information, see the Remarks section below.
        proc - A pointer to the callback function to be called for each enumerated resource name or ID. For more information, see EnumResNameProc.
        lParam - An application-defined value passed to the callback function. This parameter can be used in error checking.
        Returns:
        The return value is TRUE if the function succeeds or FALSE if the function does not find a resource of the type specified, or if the function fails for another reason. To get extended error information, call GetLastError.

      • Module32FirstW

        boolean Module32FirstW(WinNT.HANDLE hSnapshot,
                       Tlhelp32.MODULEENTRY32W lpme)
        Retrieves information about the first module associated with a process.
        Parameters:
        hSnapshot - A handle to the snapshot returned from a previous call to the CreateToolhelp32Snapshot function.
        lpme - A pointer to a MODULEENTRY32 structure.
        Returns:
        Returns TRUE if the first entry of the module list has been copied to the buffer or FALSE otherwise.
        The ERROR_NO_MORE_FILES error value is returned by the GetLastError function if no modules exist or the snapshot does not contain module information.

        MSDN

      • Module32NextW

        boolean Module32NextW(WinNT.HANDLE hSnapshot,
                      Tlhelp32.MODULEENTRY32W lpme)
        Retrieves information about the next module associated with a process or thread.
        Parameters:
        hSnapshot - A handle to the snapshot returned from a previous call to the CreateToolhelp32Snapshot function.
        lpme - A pointer to a MODULEENTRY32 structure.
        Returns:
        Returns TRUE if the first entry of the module list has been copied to the buffer or FALSE otherwise.
        The ERROR_NO_MORE_FILES error value is returned by the GetLastError function if no modules exist or the snapshot does not contain module information.

      • SetErrorMode

        int SetErrorMode(int umode)
        Controls whether the system will handle the specified types of serious errors or whether the process will handle them.
        Parameters:
        umode - The process error mode.
        Returns:
        The return value is the previous state of the error-mode bit flags.

      • GetProcAddress

        Pointer GetProcAddress(WinDef.HMODULE hmodule,
                       int ordinal)
                throws LastErrorException
        Retrieves the address of an exported function or variable from the specified dynamic-link library (DLL).

        This function is mapped to enable accessing function on win32 systems only accessible by their ordinal value.

        To access functions by their name, please use NativeLibrary#getFunction.

        Parameters:
        hmodule - A handle to the DLL module that contains the function or variable. The LoadLibrary, LoadLibraryEx, LoadPackagedLibrary, or GetModuleHandle function returns this handle.
        ordinal - ordinal value of the function export
        Returns:
        address of the exported function
        Throws:
        LastErrorException

      • SetThreadExecutionState

        int SetThreadExecutionState(int esFlags)
        Enables an application to inform the system that it is in use, thereby preventing the system from entering sleep or turning off the display while the application is running.
        Parameters:
        esFlags - The thread's execution requirements. This parameter can be one or more of the following values (ORed together)
        Returns:
        If the function succeeds, the return value is the previous thread execution state.

        If the function fails, the return value is 0
