Overview
A menu item is visible when it is in the portion of a posted menu that is mapped onto the screen (if the menu is scrollable, in particular, this portion will be smaller than the whole menu).
Portability
These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions.
