Hi,
This question is Xlib-specific, but this seems like the best place to ask: is it possible to have both XNextEvent() and glXSwapBuffers() blocking simultaneously in separate threads? glXSwapBuffers() can be set to block (via GLX extension, or at the OpenGL driver's discretion), waiting for vsync. I want to process user input and window events while this call is blocking, for that I would need to call XNextEvent() (also blocking) and associated functions from another thread. I know Xlib is not thread-safe initially, and XInitThreads() enables an internal Xlib mutex to remedy this problem. But how does this mutex interact with blocking Xlib functions? Specifically, is the lock released when they block, or do they get to execute sequentially? Is there a guaranteed behavior on this, or is it implementation dependent? I found no clear reference in the Xlib or GLX documentation.
