Functions | |
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. | |
void | unhexify (void *obuf, const char *ibuf) |
Reverse the operation performed by hexify(). |
|
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). |
|
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. |
