//  Support for variable length argument lists using the ANSI standard.
//
//  Since we are using the ANSI standard we used the standard naming and
//  did not follow the coding convention
//
//  VA_LIST  - typedef for argument list.
//  VA_START (VA_LIST Marker, argument before the ...) - Init Marker for use.
//  VA_END (VA_LIST Marker) - Clear Marker
//  VA_ARG (VA_LIST Marker, var arg size) - Use Marker to get an argument from
//    the ... list. You must know the size and pass it in this macro.
//
//  example:
//
//  UINTN
//  ExampleVarArg (
//    IN UINTN  NumberOfArgs,
//    ...
//    )
//  {
//    VA_LIST Marker;
//    UINTN   Index;
//    UINTN   Result;
//
//    //
//    // Initialize the Marker
//    //
//    VA_START (Marker, NumberOfArgs);
//    for (Index = 0, Result = 0; Index < NumberOfArgs; Index++) {
//      //
//      // The ... list is a series of UINTN values, so average them up.
//      //
//      Result += VA_ARG (Marker, UINTN);
//    }

//    VA_END (Marker);
//    return Result
