Create a window and default renderer.
Defined in <SDL3/SDL_render.h>
bool SDL_CreateWindowAndRenderer(const char *title, int width, int height, SDL_WindowFlags window_flags, SDL_Window **window, SDL_Renderer **renderer);| const char * | title | the title of the window, in UTF-8 encoding. |
| int | width | the width of the window. |
| int | height | the height of the window. |
| SDL_WindowFlags | window_flags | the flags used to create the window (see SDL_CreateWindow()). |
| SDL_Window ** | window | a pointer filled with the window, or NULL on error. |
| SDL_Renderer ** | renderer | a pointer filled with the renderer, or NULL on error. |
(bool) Returns true on success or false on failure; call SDL_GetError() for more information.
You may only call this function from the main thread.
This function is available since SDL 3.1.3.
