I've written a small program to test GNAT.Sockets.Check_Selector. After I've executed the program it immediately returns with a constraint error: raised CONSTRAINT_ERROR : g- socket.adb:538. I think the selector_type is raising this. If it doesn't return a constraint error it will run, however, Check_Selector returns immediately and Accept_Socket will block instead of accepting a socket that is ready. Any suggestions/answers/solutions to this is very appreciated.

But i didn't know how to rewrite the Check_Selector subprogram to not to use any selector_type and link it into my program. But it doesn't matter any more.
