zx_nanosleep

SUMMARY

High resolution sleep.

DECLARATION

#include <zircon/syscalls.h>

zx_status_t zx_nanosleep(zx_time_t deadline);

DESCRIPTION

zx_nanosleep() suspends the calling thread execution until deadline passes on ZX_CLOCK_MONOTONIC. A deadline value less than or equal to 0 immediately yields the thread. deadline will be automatically adjusted according to the job's [timer slack] policy.

To sleep for a duration, use [zx_deadline_after()] and the ZX_\<time-unit> helpers:

#include <zircon/syscalls.h> // zx_deadline_after, zx_nanosleep
#include <zircon/types.h> // ZX_MSEC et al.

// Sleep 50 milliseconds
zx_nanosleep(zx_deadline_after(ZX_MSEC(50)));

RIGHTS

None.

RETURN VALUE

zx_nanosleep() always returns ZX_OK.
