Hello,
I am using your code XlibNoSHM.c in https://github.com/mviereck/dockerfile-x11docker-xserver that is part of the main project https://github.com/mviereck/x11docker .

It helps me a lot! Thank you.

I am already using and publishing your code XlibNoSHM.c in x11docker/xserver.
I think of opening a new repository for just this file. Now I notice that there is no licensing information in your repository.

So I want to ask you:
Is it ok that I use your XlibNoSHM.c code already?
Is it ok if I republish it in a repository on its own? Which license should or can I use? My own projects are all published under MIT license.

Kindly regards
Martin Viereck
