LIBRARY

Standard C library (libc.so and libc.a)

SYNOPSIS

#include <sia.h>
#include <siad.h>

int siad_chk_invoker (void)

DESCRIPTION

siad_chk_invoker()

The siad_chk_invoker() routine is called to verify that the calling program is sufficiently privileged to perform security checks or security information updates. Usually only the local security mechanism is configured to  perform this check.  Although multiple mechanisms can be utilized. 

RETURN VALUES

The siad_chk_invoker() routine returns a bitmapped value which indicate the following status:

SIADSUCCESSIndicates unconditional success. All bits set to 0. 

SIADFAILIndicates conditional failure. Lowest bit set to 1.  If other security mechanism are in place, continue. 

SIADSTOPIndicates unconditional failure. Do not continue.  Second lowest bit set to 1. 

ERRORS

The errno values are those returned from the dynamic loader interface, from the (siad_∗) routines, or from malloc.  Possible errors include resource constraints (no memory) and various authentication failures.
