NAME
       dg_running_with_aa, dg_running_with_acl, dg_running_with_audit,
       dg_running_with_cap, dg_running_with_mac, - determine if the system
       is configured for the given feature

SYNOPSIS
       #include <dg_running_with.h>

       int dg_running_with_aa()

       int dg_running_with_acl()

       int dg_running_with_audit()

       int dg_running_with_cap()

       int dg_running_with_mac()

DESCRIPTION
       Use the dg_running_with function to find out if the given feature is
       configured into the currently running system.  These functions are
       contained in the libdgc.a library.

       The dg_running_with_aa function returns 1 if the system is configured
       for Trusted DG/UX Authentication and Authorization.  This is
       determined to be the case if sysconf(_SC_SEC_LEVEL) returns a value
       of _DG_C2, _DG_B1 or _DG_B2.

       The dg_running_with_acl function returns 1 if the system is
       configured for Trusted DG/UX Access Control Lists.  This is
       determined to be the case if sysconf(_SC_ACL) returns a value of
       _POSIX_ACL.

       The dg_running_with_audit function returns 1 if the system is
       configured for Trusted DG/UX Auditing.  This is determined to be the
       case if sysconf(_SC_AUD) returns a value of _DG_AUD.

       The dg_running_with_cap function returns 1 if the system is
       configured for Trusted DG/UX Least Privilege.  This is determined to
       be the case if sysconf(_SC_CAP) returns a value of _POSIX_CAP.

       The dg_running_with_mac function returns 1 if the system is
       configured for Trusted DG/UX Mandatory Access Control.  This is
       determined to be the case if sysconf(_SC_MAC) returns a value of
       _POSIX_MAC.

       These routines should be used rather than using direct calls to
       sysconf(2) because Data General reserves the right to change the
       underlying test that these routines use to detect the presence of the
       various features.

       These routines allow applications to be written that can change their
       behavior based on the configuration of the system.  If written
       correctly, the same binary image of the application can then run on

       both DG/UX and Trusted DG/UX.

EXAMPLE
       Below is an excerpt from the ttymon source code showing a change in
       behavior based on the presence of the A&A feature:

           /*
            * If host system running A&A, use -s to identify as
            * "login" service.
            */
           if (dg_running_with_aa()) {
               pmtab->p_server = "/usr/bin/login -s login";
           }
           else {
               pmtab->p_server = "/usr/bin/login";
           }
