Availability:C-language interface function

char * PL_record_external(term_t +t, size_t *len)

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_external() is called on it.

It is allowed to copy the data and use PL_recorded_external() on the copy. The user is responsible for the memory management of the copy. After copying, the original may be discarded using PL_erase_external().

PL_recorded_external() is used to copy such recorded terms back to the Prolog stack.
