oath_hex2bin - API function
#include <oath.h>
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.
