Member Function Documentation

int gr_keep_one_in_n::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.
