@ -31,6 +31,22 @@ it's the 'stop' member of SinkThreadState
return( 0 );
}
argh we have ->stop (a bool) and ->stop (a function)
rename the function as stop_fn
sstate is the "state" member of VipsThread
which is created by the ->start member of the thread
which is set by vips_threadpool_run()
which is vips_thread_state_new(), see vips_sink_memory()
which creates a VipsThreadState
so .. move ->stop from SinkThreadState into the base class, VipsThreadState
