record_t PL_record(term_t +t)

Record the term t into the Prolog database as recorda/3 and return an opaque handle to the term. The returned handle remains valid until PL_erase() is called on it. PL_recorded() is used to copy recorded terms back to the Prolog stack. Currently aborts the process with a fatal error on failure. Future versions may raise a resource exception and return (record_t)0.
