- check for an equivalent ACL
Linux Access Control Lists library (libacl, -lacl).
Fn acl_equiv_mode acl_t acl mode_t *mode_p
function checks if the ACL pointed to by the argument
contains only the required ACL entries of tag types
ACL_USER_OBJ, ACL_GROUP_OBJ, and ACL_OTHER, and contains no
permissions other that ACL_READ, ACL_WRITE or ACL_EXECUTE.
If the ACL has this form, it can can be fully represented with
the traditional file permission bits, and is considered
equivalent with the traditional file permission bits.
is an equivalent ACL and the pointer
the value pointed to by
is set to the value that defines the same owner, group and other
permissions as contained in
On success, this function returns the value
is an equivalent ACL, and the value
is not an equivalent ACL. On error, the value
is returned, and
is set appropriately.
If any of the following conditions occur, the
function returns the value
to the corresponding value:
Bq Er EINVAL
is not a valid pointer to an ACL.
This is a non-portable, Linux specific extension to the ACL manipulation
functions defined in IEEE Std 1003.1e draft 17 ("POSIX.1e", abandoned).
