SDL3

Resources

• Wiki: Main functions
  • You should always import (once) SDL_main.h, as this will handle the different entry-points that some platforms handle (e.g. WinMain)
  • You can implement everything with callbacks, instead of an entry-point defining #define SDL_MAIN_USE_CALLBACKS before importing SDL_main.h
    • The reason for doing this is that there are platforms that want to handle when a new frame is presented (e.g. iOS), or they notify when a new frame could be drawn (e.g. wayland), and so SDL handles the differences by using this callbacks.
