/*
* 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.
