multipart_open(+Stream, -DataSttream, +Options) is det

DataStream is a stream that signals end_of_file if the multipart boundary is encountered. The stream can be reset to read the next part using multipart_open_next/1. Options:

close_parent(+Boolean): Close Stream if DataStream is closed.
boundary(+Text): Define the boundary string. Text is an atom, string, code or character list.

All parts of a multipart input can be read using the following skeleton:

process_multipart(Stream) :-
      multipart_open(Stream, DataStream, [boundary(...)]),
      process_parts(DataStream).

process_parts(DataStream) :-
      process_part(DataStream),
      (   multipart_open_next(DataStream)
      ->  process_parts(DataStream)
      ;   close(DataStream)
      ).
