- * Calculate a Keccak-family hashsum of a file,
- * the content of the file is assumed non-sensitive
- * 
- * @param   fd       The file descriptor of the file to hash
- * @param   state    The hashing state, should not be initialised unless
- *                   `spec` is `NULL` (memory leak otherwise)
- * @param   spec     Specifications for the hashing algorithm; or `NULL`
- *                   if `spec` is already initialised
- * @param   suffix   The data suffix, see `libkeccak_digest`
- * @param   hashsum  Output array for the hashsum, have an allocation size of
- *                   at least `((spec->output + 7) / 8) * sizeof(char)`, may be `NULL`
- * @return           Zero on success, -1 on error
