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
Theacl_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, theacl_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, theacl_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).SEE ALSO
