   2 Basic Ascii AvSPrintf() function named VSPrint(). VSPrint() enables very
   3 simple implemenation of SPrint() and Print() to support debug.
   4
   5 You can not Print more than EFI_DRIVER_LIB_MAX_PRINT_BUFFER characters at a
   6 time. This makes the implementation very simple.
   7
   8 VSPrint, Print, SPrint format specification has the follwoing form
