Function Documentation

GR_RUNTIME_API gr_thread_t gr::thread::get_current_thread_id ( )

Get the current thread's ID as a gr_thread_t.

We use this when setting the thread affinity or any other low-level thread settings. Can be called withing a GNU Radio block to get a reference to its current thread ID.

GR_RUNTIME_API void gr::thread::mask_signals ( )

Referenced by gr::thread::thread_body_wrapper< F >::operator()().

GR_RUNTIME_API int gr::thread::set_thread_priority	(	gr_thread_t	thread,
		int	priority
	)

get current thread priority for a given thread ID

Note: this does not work on OSX

GR_RUNTIME_API void gr::thread::thread_bind_to_processor ( const std::vector< int > & mask )

Bind the current thread to a set of cores.

Wrapper for system-dependent calls to set the affinity of the current thread to the processor mask. The mask is simply a 1-demensional vector containing the processor or core number from 0 to N-1 for N cores.
