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 %
