42 | ee is not aimed at technical users; for that reason more
43 | complex features were intentionally left out. In addition,
44 | ee is intended to be compiled by people with little computer
45 | experience, which means that it needs to be small, relatively
46 | simple in implementation, and portable.

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