These system calls create and operate on a timer SYNOPSIS #include int timerfd_create(int clockid, int flags ) int timerfd_settime(int fd, int flags, const struct itimerspec * new_value, struct itimerspec * old_value ) int timerfd_gettime(int fd, struct itimerspec * curr_value ) DESCRIPTION Timerfd_create, timerfd_settime, timerfd_gettime.
