| The following structure allows menu items to be flexibly declared.
| The first item is the string describing the selection, the second
| is the address of the procedure to call when the item is selected,
| and the third is the argument for the procedure.
|
| For those systems with i18n, the string should be accompanied by a
| catalog number. The 'int *' should be replaced with 'void *' on
| systems with that type.
|
| The first menu item will be the title of the menu, with NULL
| parameters for the procedure and argument, followed by the menu items.
|
| If the procedure value is NULL, the menu item is displayed, but no
| procedure is called when the item is selected. The number of the
| item will be returned. If the third (argument) parameter is -1, no
| argument is given to the procedure when it is called.
