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 %
