Question

I want to point to a plain ole C-function from Objective-C. Specifically, I am pointing to some OpenGL functions. I want to point to this function from an entry in an NSDictionary.

So is there a way to turn a C function pointer into a SEL?

Thanks,
Doug

You could wrap it in an NSValue.

[dictionary setObject:[NSValue valueWithPointer:&myFunction] forKey:theKey];

Then when you extract it later, just call -pointerValue to get a void* pointer back (which you can cast to your function type).
