utoa32()

int fl::utoa32	(	u32	value,
		char *	buffer,
		int	radix )

Convert unsigned 32-bit integer to string buffer in given radix.

Parameters

value	The unsigned integer value to convert
buffer	Output buffer (must be at least 33 bytes for base 2, 11 for base 10, 9 for base 16)
radix	Number base (2-36, typically 10 for decimal, 16 for hex, 8 for octal)

Returns

Number of characters written (excluding null terminator)
