NAME
       dgrunningwithaa, dgrunningwithacl, dgrunningwithaudit,
       dgrunningwithmac, dgrunningwithpriv, - determine if the system
       is configured for the given feature.

SYNOPSIS
       int dgrunningwithaa()

       int dgrunningwithacl()

       int dgrunningwithaudit()

       int dgrunningwithmac()

       int dgrunningwithpriv()

DESCRIPTION
       Use the dgrunningwith 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 dgrunningwithaa function returns 1 if the system is configured
       for Trusted DG/UX Authentication and Authorization.  This is
       determined to be the case if sysconf(SCSECLEVEL) returns a value
       of DGC2, DGB1 or DGB2.

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

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

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

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

       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 (dgrunningwithaa()) {
               pmtab->pserver = "/usr/bin/login -s login";
           }
           else {
               pmtab->pserver = "/usr/bin/login";
           }
