+Module Name:
+
+ Print.c
+
+Abstract:
+
+ 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 %
