GetOpenCardName:

    This is the SDK v1.0 entry point routine to open the common dialog box.
    It has been retained for backwards compatibility; it is now a wrapper
    call for GetOpenCardNameEx().
        
Arguments:

    pOCNA - Pointer to an ANSI open card name structure.
    -or-
    pOCNW - Popinter to a UNICODE open card name structure
        
Return Value:

    A LONG value indicating the status of the requested action. Please
    see the Smartcard header files for additional information.
