The function menu_opts returns the menu's current option bits.

Ignore the case when pattern-matching.
O_SHOWMATCH-
Move the cursor to within the item name while pattern-matching.
O_NONCYCLIC-
Don't wrap around next-item and previous-item, requests to the other end of the menu.
O_MOUSE_MENU-
If user clicks with the mouse and it does not fall on the currently active menu, push KEY_MOUSE and the MEVENT data back on the queue to allow processing in another part of the calling program.

Except for menu_opts, each routine returns one of the following:
E_OK-
The routine succeeded.
E_SYSTEM_ERROR-
