Hi folks, i'm wrestling away with the schedule functions for Scheme-for-Pd, and I think I can make things a lot more reliable if I let every instantiation (or restart) of the scheme interpreter have a uid of some sort so that on a reset we can just ignore clocks running out on a previous instance instead of trying to clean them all up with manual memory management. (which approach is giving me segfaults because I'm screwing something up)

Can anyone tell me what a smart way of getting a unique identifier would be? It doesn't need to be unique across the world, just the local machine, so something that was seeded from system time would be fine. I'm not a Real C Programmer though, so am not clear what options will just work across all OS's, without needing to add dependencies.

thanks!
