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()
