t.i.t.blockingCallFromThread(reactor, f, *a, **kw) : function documentation

Run a function in the reactor from a thread, and wait for the result synchronously. If the function returns a Deferred, wait for its result and return that.

Parameters	reactor	The IReactorThreads provider which will be used to schedule the function call.
	f	the callable to run in the reactor thread (type: any callable.)
	a	the arguments to pass to f.
	kw	the keyword arguments to pass to f.
Returns	the result of the Deferred returned by f, or the result of f if it returns anything other than a Deferred.
Raises	If f raises a synchronous exception, blockingCallFromThread will raise that exception. If f returns a Deferred which fires with a Failure, blockingCallFromThread will raise that failure's exception (see Failure.raiseException).
