sdlIoFromDynamicMem function

Pointer<SdlIoStream> sdlIoFromDynamicMem()

Use this function to create an SDL_IOStream that is backed by dynamically allocated memory.

This supports the following properties to provide access to the memory and control over allocations:

  • SDL_PROP_IOSTREAM_DYNAMIC_MEMORY_POINTER: a pointer to the internal memory of the stream. This can be set to NULL to transfer ownership of the memory to the application, which should free the memory with SDL_free(). If this is done, the next operation on the stream must be SDL_CloseIO().
  • SDL_PROP_IOSTREAM_DYNAMIC_CHUNKSIZE_NUMBER: memory will be allocated in multiples of this size, defaulting to 1024.

\returns a pointer to a new SDL_IOStream structure or NULL on failure; call SDL_GetError() for more information.

\since This function is available since SDL 3.1.3.
