void hexify | ( | char * | obuf, |
const void * | ibuf, | ||
size_t | len | ||
) |
Write the contents of the binary string of length 'len' pointed to by 'ibuf' into the output buffer 'obuf' in hexadecimal format.
For example, if len==4, ibuf=="ABCDEF", then obuf will contain "41424344" with a terminating NULL character.
This is useful to turn arbitrary binary into a simple printable format, so that it can (for example) be written to a WvConf configuration file.
obuf must be a buffer with at least (len * 2) + 1 bytes available. (two digits for each byte of ibuf, plus a terminating NULL).

void unhexify | ( | void * | obuf, |
const char * | ibuf | ||
) |
Reverse the operation performed by hexify().
obuf must be a buffer large enough to contain the entire binary output string; you can calculate this size with (strlen(ibuf) / 2). obuf will NOT be automatically NULL-terminated.
