| The function <STRONG>set_menu_format</STRONG> 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, |
| <STRONG>post_menu</STRONG> will fail. |
| |
| The default format is 16 rows, 1 column. Calling <STRONG>set_menu_format</STRONG> with |
| a null menu pointer will change this default. A zero row or column |
| argument to <STRONG>set_menu_format</STRONG> is interpreted as a request not to change |
| the current value. |
| |
| The function <STRONG>menu_format</STRONG> returns the maximum-size constraints for the |
| given menu into the storage addressed by <STRONG>rows</STRONG> and <STRONG>cols</STRONG>. |
