636.0. "How to check if CDE is running?" by AOSF1::kras (Cyber-Shredder) Fri Apr 18 1997 16:34

An ISV asked me if there is any easy way to tell if CDE is running on a 
system?  They want to be able to make a check in thier code for this.

What part of CDE? The login manager? the session manager? the window 
manager? Lots of this is customizable. Here's a code snippet used by
the Sysman apps to figure out if the system is running dtwm vs mwm.

/*
 * Function:
 *      IsCDEWMRunning - returns true of dtwm is running. This is
 *      a hack for now cause there is no CDE equivalent
 *      to XmIsMotifWMRunning.
 * Inputs:
 *
 * Outputs:
 *
 * Returns:
 *      true is dtwm is running.
 * Notes:
 *      The check below relies on the DtWsmGetCurrentWorkspace function.
 *      This is only a hueristic since some other wm might
 *      emulate dtwm but it's good enough for our purposes.
