The MrmInitialize function must be called to prepare an application to use MRM widget-fetching facilities. You must call this function prior to fetching a widget. However, it is good programming practice to call MrmInitialize prior to performing any MRM operations.
MrmInitialize initializes the internal data structures that MRM needs to successfully perform type conversion on arguments and to successfully access widget creation facilities. An application must call MrmInitialize before it uses other MRM functions.
