  18 .SH DESCRIPTION
  19 .sp
  20 .LP
  21 The \fBaclcheck()\fR function checks the validity of an \fBACL\fR pointed to by
  22 \fIaclbufp.\fR The \fInentries\fR argument is the number of entries contained
  23 in the buffer. The \fIwhich\fR parameter returns the index of the first entry
  24 that is invalid.
  25 .sp
  26 .LP
  27 The function verifies that an \fBACL\fR pointed to by \fIaclbufp\fR is valid
  28 according to the following rules:
