+ * XMenu:	MIT Project Athena, X Window system menu package
+ *
+ *	XMenuPost -	Maps a given menu to the display and activates
+ *			the menu for user selection.  The user is allowed to
+ *			specify the mouse button event mask that will be used
+ *			to identify a selection request.  When a selection 
+ *			request is received (i.e., when the specified mouse
+ *			event occurs) the data  returned will be either the
+ *			data associated with the particular selection active
+ *			at the time of the selection request or NULL if no
+ *			selection was active.  A menu selection is shown to
+ *			be active by placing a highlight box around the
+ *			selection as the mouse cursor enters its active
+ *			region.  Inactive selections will not be highlighted.
+ *			As the mouse cursor moved from one menu pane
+ *			to another menu pane the pane being entered is raised
+ *			and activated and the pane being left is deactivated.
+ *			If an error occurs NULL will be returned with the
+ *			p_num set to POST_ERROR, s_num set to
+ *			NO_SELECTION and _XMErrorCode set to an
+ *			appropriate value.
+ *			Every time the routine returns successfully the
+ *			p_num and s_num indices will be set to indicate
+ *			the currently active pane and/or selection.  If the
+ *			mouse was not in a selection window at the time
+ *			s_num will be set to NO_SELECTION.
