###### (This is the legacy documentation for stable SDL2, the current stable version; [SDL3](https://wiki.libsdl.org/SDL3/) is the current development version.) # SDL_GL_LoadLibrary Dynamically load an OpenGL library. ## Syntax ```c int SDL_GL_LoadLibrary(const char *path); ``` ## Function Parameters | | | | ------------ | -------------------------------------------------------------------------------------- | | **path** | the platform dependent OpenGL library name, or NULL to open the default OpenGL library | ## Return Value Returns 0 on success or a negative error code on failure; call [SDL_GetError](SDL_GetError)() for more information. ## Remarks 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](SDL_GL_GetProcAddress)(). ## Version This function is available since SDL 2.0.0. ## Related Functions * [SDL_GL_GetProcAddress](SDL_GL_GetProcAddress) * [SDL_GL_UnloadLibrary](SDL_GL_UnloadLibrary) ---- [CategoryAPI](CategoryAPI)
