💖 SDL_GL_CreateContext(3) — SDL3 FUNCTIONS 💖

okay bestie, gather round, because this is the moment your OpenGL window stops being a sad little empty rectangle and starts being a whole vibe. This is SDL_GL_CreateContext, and she's from the SDL3 functions lineup. 🎀

✨ NAME ✨

SDL_GL_CreateContext — makes an OpenGL context for an OpenGL window, and makes it current. no cap, that's the whole gig. 💅

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_video.h>

SDL_GLContext SDL_GL_CreateContext(SDL_Window *window);

🦋 DESCRIPTION 🦋

The OpenGL context gets created using whatever current states you've set up through SDL_GL_SetAttribute(). so like, all that attribute-setting you did earlier? that's the blueprint, and this is the build. 🧚

The SDL_Window you hand over must have been created with the SDL_WINDOW_OPENGL flag, or context creation will fail. periodt. no flag, no context, that's the rule. 🙈

Windows girlies who are new to OpenGL, listen up: for historical reasons, GL functions added after OpenGL version 1.1 are not available by default. those functions have to be loaded at run-time, either with an OpenGL extension-handling library or with SDL_GL_GetProcAddress() and its related functions. it's giving "you have to go get them yourself". 😭

SDL_GLContext is opaque to the application — like, don't peek inside, she's not for you to read. ✨

💜 FUNCTION PARAMETERS 💜

  • window — the window to associate with the context. the main character of this operation fr fr. 👑

⭐ RETURN VALUE ⭐

Returns the OpenGL context associated with window, or NULL on failure. if you get NULL, call SDL_GetError() for more info — she'll tell you what went wrong. 💀

🔥 THREAD SAFETY 🔥

This function should only be called on the main thread. no side-quest threads for this one, bestie. 🫶

🌈 AVAILABILITY 🌈

This function is available since SDL 3.2.0. 👑

👑 SEE ALSO 👑

and that's the tea!! go make that context, slay your frames, and remember: every great render starts with one little SDL_GL_CreateContext. 💖✨🌸🦋
