XmIsMotifWMRunning — A function that determines whether the window manager is running

#include <Xm/Xm.h>
Boolean XmIsMotifWMRunning(
Widget shell);

XmIsMotifWMRunning lets a user know whether the Motif Window Manager is running on a screen that contains a specific widget hierarchy. This function first sees whether the _MOTIF_WM_INFO property is present on the root window of the shell's screen. If it is, its window field is used to query for the presence of the specified window as a child of root.

Specifies the shell whose screen will be tested for mwm's presence.

Returns True if MWM is running.
