		double	update_rate_ms = 500.0,
		double	alpha = 0.0001

virtual bool gr::blocks::probe_rate::start

(

)

[pure virtual]

Called to enable drivers, etc for i/o devices.

This allows a block to enable an associated driver to begin transfering data just before we start to execute the scheduler. The end result is that this reduces latency in the pipeline when dealing with audio devices, usrps, etc.

Reimplemented from gr::block.

virtual bool gr::blocks::probe_rate::stop

(

)

[pure virtual]

Called to disable drivers, etc for i/o devices.

Reimplemented from gr::block.
