Returns a menu identifier for use with other menu-related functions.

MENUID _GetNewMenuId(void any)
void any;                     /* Pointer. */

Remarks

Every menu must have a unique identifier.

For more information on how to create an API library and integrate it with Visual FoxPro, see Accessing the Visual FoxPro API.

Example

The following example builds a menu with three items. Before the example can create a menu using _NewMenu(В ), it must use _GetNewMenuId(В ) to generate a unique MENUID.
