oath_hex2bin — API function
int oath_hex2bin(const char * hexstr, char * binstr, size_t * binlen);
- const char * hexstr
input string with hex data
- char * binstr
output string that holds binary data, or NULL
- size_t * binlen
output variable holding needed length of binstr
Convert string with hex data to binary data.
Non-hexadecimal data are not ignored but instead will lead to an OATH_INVALID_HEX error.
If binstr is NULL, then binlen will be populated with the necessary length. If the binstr buffer is too small, OATH_TOO_SMALL_BUFFER is returned and binlen will contain the necessary length.
On success, OATH_OK (zero) is returned, otherwise an error code is returned.
