CREATE_MODULE(2) Linux Programmer's Manual CREATE_MODULE(2)
create_module - create a loadable module entry
#include <linux/module.h>
caddr_t create_module(const char *name, size_t size);
Note: No declaration of this system call is provided in glibc
headers; see NOTES.
Note: This system call is present only in kernels before Linux 2.6.
create_module() attempts to create a loadable module entry and
reserve the kernel memory that will be needed to hold the module.
This system call requires privilege.
On success, returns the kernel address at which the module will
reside. On error, -1 is returned and errno is set appropriately.
EEXIST A module by that name already exists.
EFAULT name is outside the program's accessible address space.
EINVAL The requested size is too small even for the module header
information.
ENOMEM The kernel could not allocate a contiguous block of memory
large enough for the module.
ENOSYS create_module() is not supported in this version of the kernel
(e.g., the kernel is version 2.6 or later).
EPERM The caller was not privileged (did not have the CAP_SYS_MODULE
capability).
This system call is present on Linux only up until kernel 2.4; it was
removed in Linux 2.6.
create_module() is Linux-specific.
This obsolete system call is not supported by glibc. No declaration
is provided in glibc headers, but, through a quirk of history, glibc
versions before 2.23 did export an ABI for this system call.
Therefore, in order to employ this system call, it was sufficient to
manually declare the interface in your code; alternatively, you could
invoke the system call using syscall(2).
