Provides services to print a formatted string to a buffer. All combinations of
Unicode and ASCII strings are supported.

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.
- RETURN_SUCCESS
- "Success"
- RETURN_LOAD_ERROR
- "Load Error"
- RETURN_INVALID_PARAMETER
- "Invalid Parameter"
- RETURN_UNSUPPORTED
- "Unsupported"
- RETURN_BAD_BUFFER_SIZE
- "Bad Buffer Size"
- RETURN_BUFFER_TOO_SMALL
- "Buffer Too Small"

/**
Converts a decimal value to a Null-terminated ASCII string.
Converts the decimal number specified by Value to a Null-terminated ASCII string
specified by Buffer containing at most Width characters. No padding of spaces
is ever performed.
If Width is 0 then a width of MAXIMUM_VALUE_CHARACTERS is assumed.
The number of ASCII characters in Buffer is returned, not including the Null-terminator.
If the conversion contains more than Width characters, then only the first Width
characters are returned, and the total number of characters required to perform
the conversion is returned.
Additional conversion parameters are specified in Flags.
The Flags bit LEFT_JUSTIFY is always ignored.
All conversions are left justified in Buffer.
If Width is 0, PREFIX_ZERO is ignored in Flags.
If COMMA_TYPE is set in Flags, then PREFIX_ZERO is ignored in Flags, and commas
are inserted every 3rd digit starting from the right.
If RADIX_HEX is set in Flags, then the output buffer will be
formatted in hexadecimal format.
If Value is < 0 and RADIX_HEX is not set in Flags, then the fist character in Buffer is a '-'.
If PREFIX_ZERO is set in Flags and PREFIX_ZERO is not being ignored,
then Buffer is padded with '0' characters so the combination of the optional '-'
sign character, '0' characters, digit characters for Value, and the Null-terminator
add up to Width characters.
If Buffer is NULL, then ASSERT().
If unsupported bits are set in Flags, then ASSERT().
If both COMMA_TYPE and RADIX_HEX are set in Flags, then ASSERT().
If Width >= MAXIMUM_VALUE_CHARACTERS, then ASSERT()
@param Buffer A pointer to the output buffer for the produced Null-terminated
ASCII string.
@param Flags The bitmask of flags that specify left justification, zero pad, and commas.
@param Value The 64-bit signed value to convert to a string.
@param Width The maximum number of ASCII characters to place in Buffer, not including
the Null-terminator.
@return The number of ASCII characters in Buffer, not including the Null-terminator.
