NAME
acl_is_trivial_np —
determine whether ACL is
trivial
LIBRARY
library “libc”
SYNOPSIS
#include
<sys/types.h>
#include <sys/acl.h>
int
acl_is_trivial_np(const
acl_t aclp, int
*trivialp);
DESCRIPTION
Theacl_is_trivial()
function determines whether the ACL pointed to by the argument
acl is trivial. Upon successful completion, the location
referred to by the argument trivialp will be set to 1,
if the ACL aclp points to is trivial, or 0 if it's not.
ACL is trivial if it can be fully expressed as a
file mode without losing any access rules. For POSIX.1e ACLs, ACL is trivial
if it has the three required entries, one for owner, one for owning group,
and one for other. For NFSv4 ACLs, ACL is trivial if it is identical to the
ACL generated by
acl_strip_np(3).
Files that have non-trivial ACL have a plus sign appended after mode bits in
"ls -l" output.
RETURN VALUES
The acl_get_tag_type() function returns
the value 0 if successful; otherwise the value -1 is returned
and the global variable errno is set to indicate the
error.

STANDARDS
POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion of the draft continues on the cross-platform POSIX.1e implementation mailing list. To join this list, see the FreeBSD POSIX.1e implementation page for more information.
HISTORY
POSIX.1e support was introduced in FreeBSD
4.0. The acl_is_trivial_np() function was
added in FreeBSD 8.0.
