## Member Function Documentation

int gr_nop::general_work | ( | int | noutput_items,
|  | gr_vector_int & | ninput_items,
|  | gr_vector_const_void_star & | input_items,
|  | gr_vector_void_star & | output_items
| ) | `[virtual]`

  | compute output items from input items Parameters:
  | noutput_items | number of output items to write on each output stream
  | ninput_items | number of input items available on each input stream
  | input_items | vector of pointers to the input items, one entry per input stream
  | output_items | vector of pointers to the output items, one entry per output stream
Returns: number of items actually written to each output stream, or -1 on EOF. It is OK to return a value less than noutput_items. -1 <= return value <= noutput_items general_work must call consume or consume_each to indicate how many items were consumed on each input stream. Implements gr_block.
