Creating an independent draw thread using pthreads (C++)
- by sagekilla
Hi all, I'm working on a graphical application which looks something like this:
while (Simulator.simulating)
{
Simulator.update();
InputManager.processInput();
VideoManager.draw();
}
I do this several times a second, and in the vast majority of cases my computation will be taking up 90 - 99% of my processing time. What I would like to do is take out the processInput and draw functions and have each one run independently.
That way, I can have the input thread always checking for input (at a reasonable rate), and the draw thread attempting to redraw at a given frame rate.
My issue is I'm not sure how I can properly do this. How would I properly initialize my pthread_t and associated pthread_attr_t so that the thread runs without blocking what I'm doing?
Any help or even a link is appreciated, thanks!
