annotate include/SDL_loadso.h @ 3235:d35b649858e0

David Carre to Sam Hello sam, me again. I'v fixed another bug in the pandora code, it's on the no-X videodriver, i forgot to add some code to destroy the window so it was impossible to reload SDL inside the same application (eglTerminate). You'll find the svn diff attached. See you, David.
