.SH DESCRIPTION
.sp
.LP
The \fIaclbufp\fR argument points to a buffer containing \fBACL\fR entries. The \fInentries\fR argument specifies the number of \fBACL\fR entries in the buffer. The \fIcalclass\fR argument, if non-zero, indicates that the \fBCLASS_OBJ\fR (\fBACL\fR mask) permissions should be recalculated. The union of the permission bits associated with all \fBACL\fR entries in the buffer other than \fBCLASS_OBJ\fR, \fBOTHER_OBJ\fR, and \fBUSER_OBJ\fR is calculated. The result is copied to the permission bits associated with the \fBCLASS_OBJ\fR entry.
.sp
.LP
The \fBaclsort()\fR function sorts the contents of the \fBACL\fR buffer as follows:
.RS +4
.TP
.ie t \(bu
.el o
Entries will be in the order \fBUSER_OBJ\fR, \fBUSER\fR, \fBGROUP_OBJ\fR, \fBGROUP\fR, \fBCLASS_OBJ\fR (\fBACL\fR mask), \fBOTHER_OBJ\fR, \fBDEF_USER_OBJ\fR, \fBDEF_USER\fR, \fBDEF_GROUP_OBJ\fR, \fBDEF_GROUP\fR, \fBDEF_CLASS_OBJ\fR (default \fBACL\fR mask), and \fBDEF_OTHER_OBJ\fR.
.RE
.RS +4
.TP
.ie t \(bu
.el o
Entries of type \fBUSER\fR, \fBGROUP\fR, \fBDEF_USER\fR, and \fBDEF_GROUP\fR will be sorted in increasing order by \fBID\fR.
.RE
.sp
.LP
The \fBaclsort()\fR function will succeed if all of the following are true:
.RS +4
.TP
.ie t \(bu
.el o
There is exactly one entry each of type \fBUSER_OBJ\fR, \fBGROUP_OBJ\fR, \fBCLASS_OBJ\fR (\fBACL\fR mask), and \fBOTHER_OBJ\fR.
.RE
.RS +4
.TP
.ie t \(bu
.el o
There is exactly one entry each of type \fBDEF_USER_OBJ\fR, \fBDEF_GROUP_OBJ\fR, \fBDEF_CLASS_OBJ\fR (default \fBACL\fR mask), and \fBDEF_OTHER_OBJ\fR if there are any default entries.
.RE
.RS +4
.TP
.ie t \(bu
.el o
Entries of type \fBUSER\fR, \fBGROUP\fR, \fBDEF_USER\fR, or \fBDEF_GROUP\fR may not contain duplicate entries. A duplicate entry is one of the same type containing the same numeric \fBID\fR.
.RE
.SH RETURN VALUES
.sp
.LP
Upon successful completion, the function returns \fB0\fR. Otherwise, it returns \fB\(mi1\fR\&.
