-Basic Ascii AvSPrintf() function named VSPrint(). VSPrint() enables very\r
-simple implemenation of SPrint() and Print() to support debug.\r
-\r
-You can not Print more than EFI_DRIVER_LIB_MAX_PRINT_BUFFER characters at a\r
-time. This makes the implementation very simple.\r
-\r
-VSPrint, Print, SPrint format specification has the follwoing form\r
-\r
-%type\r
-\r
-type:\r
- 'S','s' - argument is an Unicode string\r
- 'c' - argument is an ascii character\r
- '%' - Print a %\r
