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
|
||||
|
||||
%[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 %
