◆ BasePrintLibConvertValueToString()

UINTN BasePrintLibConvertValueToString	(	IN OUT CHAR8 *	Buffer,
		IN UINTN	Flags,
		IN INT64	Value,
		IN UINTN	Width,
		IN UINTN	Increment
	)

Internal function that converts a decimal value to a Null-terminated string.

Converts the decimal number specified by Value to a Null-terminated string specified by Buffer containing at most Width characters. If Width is 0 then a width of MAXIMUM_VALUE_CHARACTERS is assumed. The total number of characters placed in Buffer is returned. 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 Value is < 0, 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 Width >= MAXIMUM_VALUE_CHARACTERS, then ASSERT()

Parameters

Buffer	The pointer to the output buffer for the produced Null-terminated string.
Flags	The bitmask of flags that specify left justification, zero pad, and commas.
Value	The 64-bit signed value to convert to a string.
Width	The maximum number of characters to place in Buffer, not including the Null-terminator.
Increment	Character increment in Buffer.

Returns: Total number of characters required to perform the conversion.

◆ BasePrintLibConvertValueToStringS()

RETURN_STATUS BasePrintLibConvertValueToStringS	(	IN OUT CHAR8 *	Buffer,
		IN UINTN	BufferSize,
		IN UINTN	Flags,
		IN INT64	Value,
		IN UINTN	Width,
		IN UINTN	Increment
	)

Internal function that converts a decimal value to a Null-terminated string.

Converts the decimal number specified by Value to a Null-terminated string specified by Buffer containing at most Width characters. If Width is 0 then a width of MAXIMUM_VALUE_CHARACTERS is assumed. If the conversion contains more than Width characters, then only the first Width characters are placed in Buffer. 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 Value is < 0, 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 an error would be returned, the function will ASSERT().

Parameters

Buffer	The pointer to the output buffer for the produced Null-terminated string.
BufferSize	The size of Buffer in bytes, including the Null-terminator.
Flags	The bitmask of flags that specify left justification, zero pad, and commas.
Value	The 64-bit signed value to convert to a string.
Width	The maximum number of characters to place in Buffer, not including the Null-terminator.
Increment	The character increment in Buffer.

Return values

RETURN_SUCCESS	The decimal value is converted.
RETURN_BUFFER_TOO_SMALL	If BufferSize cannot hold the converted value.
RETURN_INVALID_PARAMETER	If Buffer is NULL. If Increment is 1 and PcdMaximumAsciiStringLength is not zero, BufferSize is greater than PcdMaximumAsciiStringLength. If Increment is not 1 and PcdMaximumUnicodeStringLength is not zero, BufferSize is greater than (PcdMaximumUnicodeStringLength * sizeof (CHAR16) + 1). If unsupported bits are set in Flags. If both COMMA_TYPE and RADIX_HEX are set in Flags. If Width >= MAXIMUM_VALUE_CHARACTERS.

◆ BasePrintLibFillBuffer()

CHAR8 * BasePrintLibFillBuffer	(	OUT CHAR8 *	Buffer,
		IN CHAR8 *	EndBuffer,
		IN INTN	Length,
		IN UINTN	Character,
		IN INTN	Increment
	)

Internal function that places the character into the Buffer.

Internal function that places ASCII or Unicode character into the Buffer.

Parameters

Buffer	Buffer to place the Unicode or ASCII string.
EndBuffer	The end of the input Buffer. No characters will be placed after that.
Length	The count of character to be placed into Buffer. (Negative value indicates no buffer fill.)
Character	The character to be placed into Buffer.
Increment	The character increment in Buffer.

Returns: Buffer Buffer filled with the input Character.

Internal function that places the character into the Buffer.

Internal function that places ASCII or Unicode character into the Buffer.

Parameters

Buffer	The buffer to place the Unicode or ASCII string.
EndBuffer	The end of the input Buffer. No characters will be placed after that.
Length	The count of character to be placed into Buffer. (Negative value indicates no buffer fill.)
Character	The character to be placed into Buffer.
Increment	The character increment in Buffer.

Returns: Buffer.

◆ BasePrintLibSPrint()

UINTN EFIAPI BasePrintLibSPrint	(	OUT CHAR8 *	StartOfBuffer,
		IN UINTN	BufferSize,
		IN UINTN	Flags,
		IN CONST CHAR8 *	FormatString,
			...
	)

Worker function that produces a Null-terminated string in an output buffer based on a Null-terminated format string and variable argument list.

VSPrint function to process format and place the results in Buffer. Since a VA_LIST is used this routine allows the nesting of Vararg routines. Thus this is the main print working routine

Parameters

StartOfBuffer	The character buffer to print the results of the parsing of Format into.
BufferSize	The maximum number of characters to put into buffer. Zero means no limit.
Flags	Initial flags value. Can only have FORMAT_UNICODE and OUTPUT_UNICODE set
FormatString	Null-terminated format string.
...	The variable argument list.

Returns: The number of characters printed.

Parameters

StartOfBuffer	The character buffer to print the results of the parsing of Format into.
BufferSize	The maximum number of characters to put into buffer. Zero means no limit.
Flags	Initial flags value. Can only have FORMAT_UNICODE and OUTPUT_UNICODE set
FormatString	A Null-terminated format string.

◆ BasePrintLibSPrintMarker()

UINTN BasePrintLibSPrintMarker	(	OUT CHAR8 *	Buffer,
		IN UINTN	BufferSize,
		IN UINTN	Flags,
		IN CONST CHAR8 *	Format,
		IN VA_LIST VaListMarker	OPTIONAL,
		IN BASE_LIST BaseListMarker	OPTIONAL
	)

Worker function that produces a Null-terminated string in an output buffer based on a Null-terminated format string and a VA_LIST argument list.

VSPrint function to process format and place the results in Buffer. Since a VA_LIST is used this routine allows the nesting of Vararg routines. Thus this is the main print working routine.

If COUNT_ONLY_NO_PRINT is set in Flags, Buffer will not be modified at all.

Parameters

[out]	Buffer	The character buffer to print the results of the parsing of Format into.
[in]	BufferSize	The maximum number of characters to put into buffer.
[in]	Flags	Initial flags value. Can only have FORMAT_UNICODE, OUTPUT_UNICODE, and COUNT_ONLY_NO_PRINT set.
[in]	Format	A Null-terminated format string.
[in]	VaListMarker	VA_LIST style variable argument list consumed by processing Format.
[in]	BaseListMarker	BASE_LIST style variable argument list consumed by processing Format.

Returns: The number of characters printed not including the Null-terminator. If COUNT_ONLY_NO_PRINT was set returns the same, but without any modification to Buffer.
