SDL provides functions for creating threads, mutexes, semphores and condition variables.

In general, you must be very aware of concurrency and data integrity issues +when writing multi-threaded programs. Some good guidelines include: +

Note: SDL's threading is not implemented on MacOS, due to that lack of preemptive thread support (Mac OS X dos nt suffer from this problem)
