Nanosleep

Suspends execution for a relative time interval.

Module: Linux

Signature

func Nanosleep(req: *const Timespec, rem: *Timespec) -> int64;

Parameters

Name	Type	Description
req	*const Timespec	Requested relative duration.
rem	*Timespec	Receives remaining time if interrupted, or null.

Returns

int64 — 0 after the requested interval elapses, or a negative errno result on failure or interruption.

Description

req.tv_nsec must be between 0 and 999999999. When a signal interrupts the sleep, Linux returns a negative EINTR result and, when rem is non-null, writes the unslept duration to rem.

Example

import Linux::{ IsError, Nanosleep, Timespec };

var delay = Timespec { tv_sec: 1i64, tv_nsec: 0i64 };
if IsError(Nanosleep(&delay, null)) {
    return 1i32;
}
