.SH "DESCRIPTION"
.PP
Look up an AVC entry that is valid for the
\fIrequested\fR permissions between the SID pair
(\fIssid\fR, \fItsid\fR), interpreting the permissions
based on \fItclass\fR\&.  If a valid AVC entry exists,
then this function updates \fIaeref\fR to refer to the
entry and returns 0\&. Otherwise, this function
returns -ENOENT\&.
