to_hex_string

Converts a number to a hex string. Out buffer can be same as in buffer.

Note that the character range used is a 16 item table of:

0123456789abcdef

This lets one pack one byte of input into two bytes of output.

size_t utils::to_hex_string(char * out, size_t outlen, const char * _in,
                     size_t inlen)

Type	Concept	Name	Description
char *		out
size_t		outlen
const char *		_in
size_t		inlen

#include <boost/afio/v2/afio.hpp>

O(N) where N is the length of the number.

Throws exception if output buffer is too small for input.
