I have noticed that if I do not call exit() in the POSIX_Init() function, RTEMS executables will hang. Why must I call exit() to exit the POSIX_Init() function rather than conclude with a “return” statement?
Calling exit() and returning from a POSIX thread are two totally different things. If you call exit(), then you terminate the system. If you return from a POSIX thread, then this thread exits. The scheduler just picks up the next highest priority ready thread. This could be the idle thread.
