ACL_EQUIV_MODE(3)					   BSD Library Functions Manual 					 ACL_EQUIV_MODE(3)

NAME

     acl_equiv_mode -- check for an equivalent ACL

LIBRARY

     Linux Access Control Lists library (libacl, -lacl).

SYNOPSIS

     #include <sys/types.h>
     #include <acl/libacl.h>

     int
     acl_equiv_mode(acl_t acl, mode_t *mode_p);

DESCRIPTION

     The acl_equiv_mode() function checks if the ACL pointed to by the argument acl 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 per-
     mission bits.

     If acl is an equivalent ACL and the pointer mode_p is not NULL, the value pointed to by mode_p is set to the value that defines the same
     owner, group and other permissions as contained in the ACL.

RETURN VALUE

     On success, this function returns the value 0 if acl is an equivalent ACL, and the value 1 if acl is not an equivalent ACL. On error, the
     value -1 is returned, and errno is set appropriately.

ERRORS

     If any of the following conditions occur, the acl_equiv_mode() function returns the value -1 and sets errno to the corresponding value:

     [EINVAL]		The argument acl is not a valid pointer to an ACL.

STANDARDS

     This is a non-portable, Linux specific extension to the ACL manipulation functions defined in IEEE Std 1003.1e draft 17 ("POSIX.1e", aban-
     doned).
