* Claim ownership of temporary event memory allocated by SDL.

*
* If the memory isn't temporary, or it was allocated on a different thread, this will return NULL, and the application does not have ownership of the memory.

* Note that even if a function follows the SDL_GetStringRule it may not be using temporary event memory, and this function will return NULL in that case.
