Another is to do something like this (excerpted from send_process ()).

                      int offset = 0;
[...]
                      /* Running filters might relocate buffers or strings.
                         Arrange to relocate BUF.  */
                      if (BUFFERP (object))
                        offset = BUF_PTR_BYTE_POS (XBUFFER (object), buf);
                      else if (STRINGP (object))
                        offset = buf - SDATA (object);

#ifdef EMACS_HAS_USECS
                      wait_reading_process_output (0, 20000, 0, 0, Qnil, NULL, 
0);
#else
                      wait_reading_process_output (1, 0, 0, 0, Qnil, NULL, 0);
#endif

                      if (BUFFERP (object))
                        buf = BUF_BYTE_ADDRESS (XBUFFER (object), offset);
                      else if (STRINGP (object))
                        buf = offset + SDATA (object);
