The user must override work to define the signal processing code

Implements gr_sync_block.

bool gr_oscope_sink_f::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.

References gr_oscope_sink_x::d_guts, and gr_oscope_sink_x::d_sampling_rate.
