Detailed Description

audio sink using JACK

The sink has one input stream of floats.

Input samples must be in the range [-1,1].

Member Function Documentation

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

Confirm that ninputs and noutputs is an acceptable combination. Parameters: ninputs  number of input streams connected noutputs  number of output streams connected Returns: true if this is a valid configuration for this block. This function is called by the runtime system whenever the topology changes. Most classes do not need to override this. This check is in addition to the constraints specified by the input and output gr_io_signatures. Reimplemented from gr_basic_block.

int audio_jack_sink::work (  int  noutput_items, gr_vector_const_void_star &  input_items, gr_vector_void_star &  output_items )  [virtual]

just like gr_block::general_work, only this arranges to call consume_each for you The user must override work to define the signal processing code Implements gr_sync_block.
