This function affects Menu-Manager (mode-specific) menus only.

The recommended way of adding new items to the standard Creo Parametric menus is as follows:

• The menu menuname must have been loaded via ProMenuFileRegister() before this function can be called, and it cannot be active on the screen at the time of this call.
• The argument filename must be different from the standard Creo Parametric menu name.
• The contents of filename must adhere to the Creo Parametric menu standards. Specifically, the first three lines must be the same as the Creo Parametric menu file, after which this file need only contain your additions.
