Member Function Documentation

void gr_simple_framer::forecast (  int  noutput_items, gr_vector_int &  ninput_items_required )  [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.

int gr_simple_framer::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.
