from_hex_string

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

Note that this routine is about 43% slower than to_hex_string(), half of which is due to input validation.

size_t utils::from_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 string.

Throws exception if output buffer is too small for input or input size is not multiple of two.
