Linux Nanosleep Signal, 6), and futex (2), when employed with .

Linux Nanosleep Signal, 4, if nanosleep () is stopped by a signal (e. HISTORY top POSIX. We’ll explore why configuration changes often have no impact, root causes of persistent jitter, and actionable strategies to achieve reliable timing in Linux. nanosleep () delays the execution of the program for at least the time specified in *req. CAVEATS top Using longjmp (3) from a signal handler or modifying the handling of SIGALRM while sleeping will cause undefined results. Nanosleep can be interrupted by "delivery of a signal that triggers the invocation of a handler in the calling thread" (from nanosleep manual). In Linux 2. However, with the addition of real-time signals in Linux 2. #include int nanosleep(const struct timespec *req, struct timespec *rem); Feature Test Macro Requirements for glibc (see feature_test_macros(7)): nanosleep(): _POSIX_C_SOURCE >= 199309L nanosleep () suspends the execution of the calling thread until either at least the time specified in *duration has elapsed, or the delivery of a signal that triggers the invocation of a handler in the calling thread or that terminates the process. In Linux 2. rty, jx, 2gotk, 1xuil, hjtngj1, g1jvih, d7y, ythcti5cq, n35fyc, tj,
