-/** @file

-Basic Ascii AvSPrintf() function named VSPrint(). VSPrint() enables very

-simple implemenation of SPrint() and Print() to support debug.

-

-You can not Print more than EFI_DRIVER_LIB_MAX_PRINT_BUFFER characters at a

-time. This makes the implementation very simple.

-

-VSPrint, Print, SPrint format specification has the follwoing form

-

-%type

-

-type:

-  'S','s' - argument is an Unicode string

-  'c' - argument is an ascii character

-  '%' - Print a %
