ACL_CMP(3) BSD Library Functions Manual ACL_CMP(3)
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 en-
try 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).
