Thanks Ka, Varriout. Speed is not a concern as my controls gui2 is more of a designer for the 3d objects in a design mode. (sliders to manipulate a 3d objects size, orientation etc which I then need to pass/reflect in the opengl gui1)
> >So its better and safer to use pipes, shared memory, fifos etc. By pipes, do you mean nim Channels? Shared memory / fifos - are there any examples? - I know I could use a seq for the messages or the nim queues module, or maybe even a one-size fits all shared struct, but it's the sharing of the struct/queue that's problematic. I will continue tinkering, many thanks all...
