SDL 1.3 opengl release context

Hi,

I see that, currently, there is no way to release a gl context in the
SDL1.3 branch.

This would be a useful feature for people who want to render in a
different thread and not have to go through platform specific code.

A new function could be added, or maybe SDL could expose a 'NULL’
SDL_GLContext to pass to SLD_GL_MakeCurrent to release the context?

Hi,

I’m not sure what you mean…

To make the current context NULL, you can do:
SDL_GL_MakeCurrent(0, NULL);

To delete the context, you can do:
SDL_GL_DeleteContext(context);

In fact, to clean up a context you must do both, as shown in SDL_compat.c

Oh. I missed that. I did not think you could pass NULL to
SDL_GL_MakeCurrent and remove the context from the current thread.

That’s all I wanted :slight_smile: SDL 1.3 will be great!
