| | [virtual] |
Estimate input requirements given output request.
- Parameters:
-
| noutput_items | number of output items to produce |
| ninput_items_required | number of input items required on each input stream |
Given a request to product noutput_items
, estimate the number of data items required on each input stream. The estimate doesn't have to be exact, but should be close.
Reimplemented from gr_block.

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.
