NAME

oath_hex2bin - API function

SYNOPSIS

#include <oath.h>

int oath_hex2bin(const char * hexstr, char * binstr, size_t * binlen);

ARGUMENTS

input string with hex data
output string that holds binary data, or NULL
output variable holding needed length of binstr

DESCRIPTION

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.

RETURNS

On success, OATH_OK (zero) is returned, otherwise an error code is returned.
