The Print Library functions provide a simple means to produce formatted output
|
|
strings. Many of the output functions use a format string to describe how to
|
|
format the output of variable arguments. The format string consists of normal
|
|
text and argument descriptors. There are no restrictions for how the normal
|
|
text and argument descriptors can be mixed. The following end of line(EOL)
|
|
translations must be performed on the contents of the format string:
|
|
|
|
- '\\r' is translated to '\\r'
|
|
- '\\r\\n' is translated to '\\r\\n'
|
|
- '\\n' is translated to '\\r\\n'
|
|
- '\\n\\r' is translated to '\\r\\n'
|
|
|
|
This does not follow the ANSI C standard for sprint(). The format of argument
|
|
descriptors is described below. The ANSI C standard for sprint() has been
|
|
followed for some of the format types, and has not been followed for others.
|
|
The exceptions are noted below.
|
|
|
|
%[flags][width][.precision]type
|
|
|
|
[flags]:
|
|
- -
|
|
- The field is left justified. If not flag is not specified, then the
|
|
field is right justified.
|
|
- space
|
|
- Prefix a space character to a number. Only valid for types X, x, and d.
|
|
- +
|
|
- Prefix a plus character to a number. Only valid for types X, x, and d.
|
|
If both space and + are specified, then space is ignored.
|
|
- 0
|
|
- Pad with 0 characters to the left of a number. Only valid for types
|
|
X, x, and d.
|
|
- ,
|
|
- Place a comma every 3rd digit of the number. Only valid for type d.
|
|
If 0 is also specified, then 0 is ignored.
|
|
- L, l
|
|
- The number being printed is size UINT64. Only valid for types X, x, and d.
|
|
If this flag is not specified, then the number being printed is size int.
|
|
- NOTE: All invalid flags are ignored.
|
|
|
|
[width]:
|
|
|
|
- *
|
|
- The width of the field is specified by a UINTN argument in the
|
|
argument list.
|
|
- number
|
|
- The number specified as a decimal value represents the width of
|
|
the field.
|
|
- NOTE: If [width] is not specified, then a field width of 0 is assumed.
|
|
|
|
[.precision]:
|
|
|
|
- *
|
|
- The precision of the field is specified by a UINTN argument in the
|
|
argument list.
|
|
- number
|
|
- The number specified as a decimal value represents the precision of
|
|
the field.
|
|
- NOTE: If [.precision] is not specified, then a precision of 0 is assumed.
|
|
|
|
type:
|
|
|
|
- %
|
|
- Print a %%.
|
|
- c
|
|
- The argument is a Unicode character. ASCII characters can be printed
|
|
using this type too by making sure bits 8..15 of the argument are set to 0.
|
|
- x
|
|
- The argument is an unsigned hexadecimal number. The characters used are 0..9 and
|
|
A..F. If the flag 'L' is not specified, then the argument is assumed
|
|
to be size int. This does not follow ANSI C.
|
|
- X
|
|
- The argument is an unsigned hexadecimal number and the number is padded with
|
|
zeros. This is equivalent to a format string of "0x". If the flag
|
|
'L' is not specified, then the argument is assumed to be size int.
|
|
This does not follow ANSI C.
|
|
- d
|
|
- The argument is a signed decimal number. If the flag 'L' is not specified,
|
|
then the argument is assumed to be size int.
|
|
- u
|
|
- The argument is a unsigned decimal number. If the flag 'L' is not specified,
|
|
then the argument is assumed to be size int.
|
|
- p
|
|
- The argument is a pointer that is a (VOID *), and it is printed as an
|
|
unsigned hexadecimal number The characters used are 0..9 and A..F.
|
|
- a
|
|
- The argument is a pointer to an ASCII string.
|
|
This does not follow ANSI C.
|
|
- S, s
|
|
- The argument is a pointer to a Unicode string.
|
|
This does not follow ANSI C.
|
|
- g
|
|
- The argument is a pointer to a GUID structure. The GUID is printed
|
|
in the format XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX.
|
|
This does not follow ANSI C.
|
|
- t
|
|
- The argument is a pointer to an EFI_TIME structure. The time and
|
|
date are printed in the format "mm/dd/yyyy hh:mm" where mm is the
|
|
month zero padded, dd is the day zero padded, yyyy is the year zero
|
|
padded, hh is the hour zero padded, and mm is minutes zero padded.
|
|
This does not follow ANSI C.
|
|
- r
|
|
- The argument is a RETURN_STATUS value. This value is converted to
|
|
a string following the table below. This does not follow ANSI C.
|
