NAME

       acl_cmp — compare two ACLs

LIBRARY

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

SYNOPSIS

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

       int
       acl_cmp(acl_t acl1, acl_t acl2);

DESCRIPTION

       The  acl_cmp() function compares the ACLs pointed to by the arguments acl1 and acl2 for equality. The two
       ACLs are considered equal if for each entry in acl1 there is an entry in acl2  with  matching  tag  type,
       qualifier, and permissions, and vice versa.

RETURN VALUE

       If  successful,  the  acl_cmp() function returns 0 if the two ACLs acl1 and acl2 are equal, and 1 if they
       differ. Otherwise, the value -1 is returned and the global variable errno is set to indicate the error.

ERRORS

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

       [EINVAL]           The argument acl1 is not a valid pointer to an ACL.

                          The argument acl2 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”, abandoned).
