strange delete occurance

Hi, I have a problem I don't understand the behaviour.

I have a slot and there a instantiate a QList<int*>*;

Qt Code:

Switch view

void Class::slot()
{
    QList<int>* list = new QList<int>();
    qDebug() << "list_adress: " << list; //i.e. 0x7fbc24034870 
    deleteList(list);
    qDebug() << "list_adress: " << list; // i expect 0x0, but output is 0x7fbc24034870 
}
 
void Class::deleteList(QList<int>* list)
{
    delete list;
    list = NULL;
}

void Class::slot()
{
    QList<int>* list = new QList<int>();
    qDebug() << "list_adress: " << list; //i.e. 0x7fbc24034870 
    deleteList(list);
    qDebug() << "list_adress: " << list; // i expect 0x0, but output is 0x7fbc24034870 
}

void Class::deleteList(QList<int>* list)
{
    delete list;
    list = NULL;
}

To copy to clipboard, switch view to plain text mode

Why pointer is not deleted in slot?
Please help me!!??
