Hey guys & girls,

I have noticed one thing on iOS/Mac systems ( Unix-wide, I think ): When I try to initialize network socket, it takes 10-20 seconds to create. Here's code:

    
   _core.Print( LOG_INFO, "Creating network socket using udp protocol..\n" );
    if( ( NetworkSocket = socket( PF_INET, SOCK_DGRAM, IPPROTO_UDP )) == - 1 ) {
        return;
    }

On application quit I do this:

    shutdown( NetworkSocket, 2 );
    close( NetworkSocket );

On Windows it's okay, takes some milliseconds.

What may be a problem? I already tried to null the NetworkSocket. No results.

Add log-messages before and after every call on the socket and see which one takes time. (Or just add break-points in the debugger and step over the calls).

Since you show your shutdown code I assume the time is including this.. in which case I would guess that shutdown() blocks and the remote end doesn't acknowledge which causes it to wait for timeout.

I do "bind" after the socket creation. It's UDP, so I don't need to "connect".

That's strange thing, I don't think that it should take that much time.

No, it's not virtualized. My current "hardware" is MacBook. ( built-in wifi card, I don't have any adapter ) and iPhone 5s ( the same prob here ).

Aaaand I have noticed one thing: when there is no access to internet, socket freezes, but when internet connection is available, it's fast. But on i5s it's always freezes.
