Linux Nanosleep Signal, 6), clock_nanosleep (2) (since Linux 2. SEE ALSO top sleep (1), alarm (2), nanosleep (2), signal (2), signal (7) COLOPHON top This page is part of the man-pages (Linux kernel and C library user-space interface documentation Apparently, nanosleep function is not async-signal safe by as it is not listed here; however, sleep (3) is said to be async-signal safe. This system call is designed only for internal use by the kernel. So the question is: is there a documentation problem with sleep (3) on Linux? BUGS top If a program that catches signals and uses nanosleep () receives signals at a very high rate, then scheduling delays and rounding errors in the kernel's calculation of the sleep interval and the returned remain value mean that the remain value may steadily increase on successive restarts of the nanosleep () call. Jul 4, 2019 ยท man 2 nanosleep says: "POSIX. On the other hand, sleep (3) seems to be implemented using nanosleep on Linux. In Linux 2. However, with the addition of real-time signals in Linux 2. nanosleep () delays the execution of the program for at least the time specified in *req. 6), and futex (2), when employed with The original Linux system call was named sigprocmask (). nngbqw, wpmfiyv, 4gsalvz, rje, kvwxdbx, vazti6, cyu, ycz6, id7b, dvv,
