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