Member Function Documentation

virtual 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.
