Detailed Description

output[i] = input[i]

When enabled (default), this block copies its input to its output. When disabled, this block drops its input on the floor.


Member Function Documentation

bool gr_copy::check_topology ( int  ninputs,
int  noutputs 
) [virtual]

Reimplemented from gr_block.

bool gr_copy::enabled ( ) const [inline]
int gr_copy::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_itemsnumber of output items to write on each output stream
ninput_itemsnumber of input items available on each input stream
input_itemsvector of pointers to the input items, one entry per input stream
output_itemsvector 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.

Reimplemented from gr_block.
