getfilecon(3)             SELinux API documentation            getfilecon(3)

NAME         top

       getfilecon,  fgetfilecon,  lgetfilecon - get SELinux security context
       of a file

SYNOPSIS         top

       #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);

DESCRIPTION         top

       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

       The returned context should be freed with freecon(3) if non-NULL.

RETURN VALUE         top

       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
