+ Converts the decimal number specified by Value to a Null-terminated

+ 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.
