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 %

Routine Description:

|
|
VSPrint function to process format and place the results in Buffer. Since a

VA_LIST is used this rountine allows the nesting of Vararg routines. Thus

this is the main print working routine

Arguments:
|
|
|
|
StartOfBuffer - Unicode buffer to print the results of the parsing of Format into.

BufferSize - Maximum number of characters to put into buffer. Zero means

no limit.

FormatString - Unicode format string see file header for more details.
