int QProcess::execute(const QString &program, const QStringList &arguments)
    QProcess process;
    process.start(program, arguments);
    if (!process.waitForFinished(-1) || process.error() == FailedToStart)
        return -2;
    return process.exitStatus() == QProcess::NormalExit ? process.exitCode() : 

Any and all differences are there.
