sdlOpenIo function

Pointer<SdlIoStream> sdlOpenIo(Pointer<SdlIoStreamInterface> iface, Pointer<NativeType> userdata)

Create a custom SDL_IOStream.

Applications do not need to use this function unless they are providing their own SDL_IOStream implementation. If you just need an SDL_IOStream to read/write a common data source, you should use the built-in implementations in SDL, like SDL_IOFromFile() or SDL_IOFromMem(), etc.

This function makes a copy of iface and the caller does not need to keep it around after this call.

\param iface the interface that implements this SDL_IOStream, initialized using SDL_INIT_INTERFACE(). \param userdata the pointer that will be passed to the interface functions. \returns a pointer to the allocated memory on success or NULL on failure; call SDL_GetError() for more information.

\since This function is available since SDL 3.1.3.
