getmax_sl, getmax_tl, getmin_sl, and getmin_tl Subroutines

Purpose

Retrieve maximum and minimum sensitivity label (SL) and integrity label (TL) from the initialized label encodings file.

Library

Trusted AIX® Library ( libmls.a )

Syntax

#include <mls/mls.h>
int getmax_sl (sl)
sl_t *sl;

int getmax_tl (tl)
tl_t *tl;

int getmin_sl(sl)
sl_t *sl;

int getmin_tl(tl)
sl_t *tl;

Description

The getmax_sl subroutine retrieves the maximum SL that is defined in the initialized label encodings file and copies the result to the sl parameter.

The getmax_tl subroutine retrieves the maximum TL that is defined in the initialized label encodings file and copies the result to the tl parameter.

The getmin_sl subroutine retrieves the minimum SL that is defined in the initialized label encodings file and copies the result to the sl parameter.

The getmax_tl subroutine retrieves the minimum TL that is defined in the initialized label encodings file and copies the result to the tl parameter.

Requirement: Must initialize the database before running these subroutines.
