.SH NAME
acl_trivial \- determine whether a file has a trivial ACL
.SH SYNOPSIS
.LP
.nf
cc [ \fIflag\fR\&.\|.\|. ] \fIfile\fR\&.\|.\|. \fB-lsec\fR [ \fIlibrary\fR\&.\|.\|. ] 
#include <sys/acl.h>

\fBint\fR \fBacl_trivial\fR(\fBchar *\fR\fIpath\fR);

.SH DESCRIPTION
.sp
.LP
The \fBacl_trivial()\fR function is used to determine whether a file has a trivial ACL. Whether an ACL is trivial depends on the type of the ACL. A POSIX draft ACL is nontrivial if it has greater than \fBMIN_ACL_ENTRIES\fR. An NFSv4/ZFS-style ACL is nontrivial if it either has entries other than \fBowner@\fR, \fBgroup@\fR, and \fBeveryone@\fR, has inheritance flags set, or is not ordered in a manner that meets POSIX access control requirements.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, \fBacl_trivial()\fR returns 0 if the file's ACL is trivial and 1 if the file's ACL is not trivial. If it could not be determined whether a file's ACL is trivial, -1 is returned and \fBerrno\fR is set to indicate the error.
