(This is the legacy documentation for SDL2, the previous stable version; SDL3 is the current stable version.)

SDL_GL_CreateContext

Create an OpenGL context for an OpenGL window, and make it current.

Header File

Syntax

SDL_GLContext SDL_GL_CreateContext(SDL_Window *
                                   window);

Function Parameters

SDL_Window *

window

the window to associate with the context.

Return Value

(SDL_GLContext) Returns the OpenGL context associated with window or NULL on error; call SDL_GetError() for more details.

Remarks

Windows users new to OpenGL should note that, for historical reasons, GL functions added after OpenGL version 1.1 are not available by default. Those functions must be loaded at run-time, either with an OpenGL extension-handling library or with SDL_GL_GetProcAddress() and its related functions.

SDL_GLContext is an alias for void *. It's opaque to the application.

Version

This function is available since SDL 2.0.0.
