+Module Name:
+
+ Sprint.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
+
+ %[flags][width]type
+
+ flags:
+ '-' - Left justify
+ '+' - Prefix a sign
+ ' ' - Prefix a blank
+ ',' - Place commas in numberss
+ '0' - Prefix for width with zeros
+ 'l' - UINT64
+ 'L' - UINT64
+
+ width:
+ '*' - Get width from a UINTN argumnet from the argument list
+ Decimal number that represents width of print
+
+ type:
+ 'X' - argument is a UINTN hex number, prefix '0'
+ 'x' - argument is a hex number
+ 'd' - argument is a decimal number
+ 'a' - argument is an ascii string
+ 'S','s' - argument is an Unicode string
+ 'g' - argument is a pointer to an EFI_GUID
+ 't' - argument is a pointer to an EFI_TIME structure
+ 'c' - argument is an ascii character
+ 'r' - argument is EFI_STATUS
+ '%' - Print a %
