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 an error would be returned, then the function will ASSERT().
@param Buffer The pointer to the output buffer for the produced
Null-terminated Ascii string.
@param BufferSize The size of Buffer in bytes, including the
Null-terminator.
@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.
@retval RETURN_SUCCESS The decimal value is converted.
@retval RETURN_BUFFER_TOO_SMALL If BufferSize cannot hold the converted
value.
@retval RETURN_INVALID_PARAMETER If Buffer is NULL.
If PcdMaximumAsciiStringLength is not
zero, and BufferSize is greater than
PcdMaximumAsciiStringLength.
If unsupported bits are set in Flags.
If both COMMA_TYPE and RADIX_HEX are set in
Flags.
If Width >= MAXIMUM_VALUE_CHARACTERS.
