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);
