💖 SDL_GL_SwapWindow 💖

okay bestie, welcome to the SDL3 FUNCTIONS manual — and this one is literally the glow-up button for your OpenGL window. 💅✨

---

✨ NAME ✨

• SDL_GL_SwapWindow — Update a window with OpenGL rendering.

---

📜 SYNOPSIS 📜

#include <SDL3/SDL_video.h>

bool SDL_GL_SwapWindow(SDL_Window *window);

---

🌸 DESCRIPTION 🌸

So here's the tea: this function is used with double-buffered OpenGL contexts, which are the default. No cap. 🫶

On macOS, make sure you bind 0 to the draw framebuffer before swapping the window, otherwise nothing will happen. If you aren't using glBindFramebuffer(), this is the default and you won't have to do anything extra. Easy peasy. 🍓
