node-priority

node-priority

This package provides access to the getpriority(2) and setpriority(2) system calls available on OSX, Linux and other UNIX variants. This can be used, for example, to implement the UNIX nice(1) utility.

Usage

var priority = require('node-priority');
var getpriority = priority.get;
var setpriority = priority.set;

setpriority(priority.Process, 0, 10, function(err) {
    if (err)
        throw err;
    getpriority(priority.Process, 0, function(err, prio) {
        console.log('successfully set priority to ' + prio);
    });
});

setpriority(function(err, rfd, wfd) {
    if (err) {
        console.log('pipe failed, maybe out of FDs? ' + err);
        return;
    }
    // use rfd and wfd
});
