Multi-threaded Programming
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:
Don't call SDL video/event functions from separate threads Don't use any library functions in separate threads Don't perform any memory management in separate threads Lock global variables which may be accessed by multiple threads Never terminate threads, always set a flag and wait for them to quit Think very carefully about all possible ways your code may interact
Note: SDL's threading is not implemented on MacOS, due to that lack of preemptive thread support (MacOS X dos nt suffer from this problem)
