Reserve TCP port for server application?

[CAD_coding]

Hi,
I want to reserve a specific port on the server for my application so that no other application can claim that port.
How do I do this in Qt in a platform independent manner?
I am using TCP protocol and the corresponding Qt classes.

You mean you like to reserve the server port for an application while the application is not running?

[CAD_coding]

Yes.
I want to permanently reserve a port for my application while installing.
I want to do this as my client applications are hard coded for server port number.
I can then unreserve while uninstalling my application.
Is it possible to do this?

AFAIK this is too specific and OS dependent for Qt.
