SDL_IOFromDynamicMem - Use this function to create an SDL_IOStream that is backed by dynamically

       This function is available since SDL 3.2.0.

       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.

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

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