v0.4.0

Nanosleep v0.1.0

Suspends execution for a relative time interval.

Package: 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.nanoseconds 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 };

func Main() -> int {
    var delay = Timespec { seconds: 1i64, nanoseconds: 0i64 };
    if IsError(Nanosleep(@delay, null)) {
        return 1;
    }
    return 0;
}
