qt QProcessEnvironmentsystemEnvironment

The QProcessEnvironment::systemEnvironment() function is a static function that returns the environment variables of the system as a QProcessEnvironment object. The QProcessEnvironment class provides an interface for accessing and manipulating the environment variables of a process.

Here is an example usage of QProcessEnvironment::systemEnvironment():

QProcessEnvironment environment = QProcessEnvironment::systemEnvironment();
QStringList keys = environment.keys();

foreach (const QString &key, keys) {
    qDebug() << key << ": " << environment.value(key);
}

This code retrieves the system environment variables, then iterates over them and prints each key-value pair using qDebug()
