getfilecon(3) SELinux API documentation getfilecon(3)
getfilecon, fgetfilecon, lgetfilecon - get SELinux security context
of a file
#include <selinux/selinux.h>
int getfilecon(const char *path, char **con);
int getfilecon_raw(const char *path, char **con);
int lgetfilecon(const char *path, char **con);
int lgetfilecon_raw(const char *path, char **con);
int fgetfilecon(int fd, char **con);
int fgetfilecon_raw(int fd, char **con);
getfilecon() retrieves the context associated with the given path in
the file system, the length of the context is returned.
lgetfilecon() is identical to getfilecon(), except in the case of a
symbolic link, where the link itself is interrogated, not the file
that it refers to.
fgetfilecon() is identical to getfilecon(), only the open file
pointed to by filedes (as returned by open(2)) is interrogated in
place of path.
getfilecon_raw(), lgetfilecon_raw() and fgetfilecon_raw() behave
identically to their non-raw counterparts but do not perform context
translation.
The returned context should be freed with freecon(3) if non-NULL.
On success, a positive number is returned indicating the size of the
extended attribute value. On failure, -1 is returned and errno is
set appropriately.
If the context does not exist, or the process has no access to this
attribute, errno is set to ENODATA.
If extended attributes are not supported by the filesystem, or are
disabled, errno is set to ENOTSUP.
The errors documented for the stat(2) system call are also applicable
here.
