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.
