Use this function to free an SDL_RWops structure allocated by SDL_CreateRW().
void SDL_DestroyRW(SDL_RWops *context);
|context||the SDL_RWops structure to be freed|
Applications do not need to use this function unless they are providing their own SDL_RWops implementation. If you just need an SDL_RWops to read/write a common data source, you should use the built-in implementations in SDL, like SDL_RWFromFile() or SDL_RWFromMem(), etc, and call the close method on those SDL_RWops pointers when you are done with them.
Only use SDL_DestroyRW() on pointers returned by SDL_CreateRW(). The pointer is invalid as soon as this function returns. Any extra memory allocated during creation of the SDL_RWops is not freed by SDL_DestroyRW(); the programmer must be responsible for managing that memory in their close method.
This function is available since SDL 3.0.0.
