Описание (Description)
The function set_menu_format
sets the maximum display size of the
given menu. If this size is too small to display all menu items,
the menu will be made scrollable. If this size is larger than
the menus subwindow and the subwindow is too small to display all
menu items, post_menu
will fail.
The default format is 16 rows, 1 column. Calling set_menu_format
with a null menu pointer will change this default. A zero row or
column argument to set_menu_format
is interpreted as a request
not to change the current value.
The function menu_format
returns the maximum-size constraints for
the given menu into the storage addressed by rows
and cols
.
