Expand description

\brief Dynamically load an OpenGL library.

\param path The platform dependent OpenGL library name, or NULL to open the default OpenGL library.

\return 0 on success, or -1 if the library couldn’t be loaded.

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.

\note 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().
