|
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 HEX_RADIX is set in Flags, then the output buffer will be
|
|
formatted in hexadecimal format.
|
|
If Value is < 0 and HEX_RADIX 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 HEX_RADIX are set in Flags, then ASSERT().
|
|
If Width >= MAXIMUM_VALUE_CHARACTERS, then ASSERT()
|
|
|
|
@param Buffer 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.
