SDL_IOFromMem - Use this function to prepare a read-write memory buffer for use with SDL_IOStream .

       This function is available since SDL 3.2.0.

       This function sets up an SDL_IOStream
        struct based on a memory area of a certain size, for both read and write access.

       This  memory  buffer  is not copied by the SDL_IOStream ; the pointer you provide must remain valid until
       you close the stream. Closing the stream will not free the original buffer.

       If you need to make sure the SDL_IOStream
        never writes to the memory buffer, you should use

       SDL_IOFromConstMem () with a read-only buffer of memory instead.

       The following properties will be set at creation time by SDL:

       • SDL_PROP_IOSTREAM_MEMORY_POINTER :
         this will be the mem parameter that was passed to this function.

       • SDL_PROP_IOSTREAM_MEMORY_SIZE_NUMBER :
         this will be the size parameter that was passed to this function.

mem    a pointer to a buffer to feed an SDL_IOStream
               stream.

       size   the buffer size, in bytes.
