Contrary to popular belief, we are not all-knowing-all-seeing magical beings!

If you want help you're going to have to provide lots of info. Like what is your hardware, what is your operating system, what version of GZDoom/LZDoom/whatever you're using, what mods you're loading, how you're loading it, what you've already tried for fixing the problem, and anything else that is even remotely relevant to the problem.

We can't magically figure out what it is if you're going to be vague, and if we feel like you're just wasting our time with guessing games we will act like that's what you're really doing and won't help you.

ZDOOM "Could not create socket : EINVAL"

Post by chandan123 »

When trying to connect two computers, after succesfully connecting, the zdoom launch console creates an error that says,
"Could not create socket : EINVAL"
To clarify, both computers enter the zdoom launcher and start to go through the launch process, but then the error occurs.
Is this something with the computer or internet? Any help would be appreciated.

What version of ZDoom is being run? Which OS are you using? How is the game being launched?

EINVAL means "error: invalid argument".
Here's the function which prints this error message:

Code: Select all

// UDPsocket
SOCKET UDPsocket (void)
	// allocate a socket
		I_FatalError ("can't create socket: %s", neterror ());

	return s;
This is the extent of the help I can provide. For some reason your system doesn't support creating the type of socket that ZDoom wants to make.
