posix_period_init
rte_status_t posix_period_init(struct timespec *out_deadline)
Starts a period: reads CLOCK_MONOTONIC into the deadline.
Definition rte_posix_osadapter_period.c:70

posix_period_wake_all
void posix_period_wake_all(volatile sig_atomic_t *should_stop)
Requests a stop of a periodic thread and wakes it from its wait.
Definition rte_posix_osadapter_period.c:139

posix_period_wake_ready
bool posix_period_wake_ready(void)
Creates the process-wide wake object on the first call; true once it exists.
Definition rte_posix_osadapter_period.c:127

posix_period_sleep_until
rte_status_t posix_period_sleep_until(const struct timespec *deadline, const volatile sig_atomic_t *should_stop)
Waits until the absolute CLOCK_MONOTONIC deadline, or until a stop is requested.
Definition rte_posix_osadapter_period.c:109

posix_period_advance
void posix_period_advance(struct timespec *deadline, rte_duration_ms_t period_ms)
Moves the deadline one period later, keeping tv_nsec in [0, 1 s).
Definition rte_posix_osadapter_period.c:92
