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. Since libselinux 3.4 a file opened via O_PATH is
supported.
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.
