how to use "argc" and "argv" ?

[probine]

I have a main.cpp class

#include <QApplication>
#include "server.h"
 
int main(int argc, char * argv[])
{
  QApplication app(argc, argv);
  Server * server;
  server = new Server();
  return app.exec();
}

#include <QApplication>
#include "server.h"

int main(int argc, char * argv[])
{
  QApplication app(argc, argv);
  Server * server;
  server = new Server();
  return app.exec();
}

To copy to clipboard, switch view to plain text mode 

At this point, I presume, the "app" instance has been inputed with the "argc" and "argv".

How can I use this variables in my "server" instance ?
