Expand description

Dynamically load an OpenGL library.

This should be done after initializing the video driver, but before creating any OpenGL windows. If no OpenGL library is loaded, the default library will be loaded upon creation of the first OpenGL window.

If you do this, you need to retrieve all of the GL functions used in your program from the dynamic library using SDL_GL_GetProcAddress().

\param path the platform dependent OpenGL library name, or NULL to open the default OpenGL library \returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.

\since This function is available since SDL 2.0.0.
