mitem_visible - check visibility of a menu item
#include <menu.h> bool item_visible(const ITEM *item);
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).
The header file <menu.h> automatically includes the header file <curses.h>.
These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions.
