CppSharp generates incorrect bindings for SDL_Event #978
Description
CppSharp with SDL generates the wrong bindings.
This is the equivalent C code:
SDL_Event event;
while(SDL_WaitEvent(&event))
{
if(e.type = SDL_QUIT)
exit(0);
}One should expect to get it working with something like this:
SDL.SDL_Event e = new SDL.SDL_Event();
while(SDL.SDL_WaitEvent(e))
{
if(e.Type == (uint)SDL.SDL_EventType.SDL_QUIT)
System.Environment.Exit(0);
}But SDL.SDL_Event is a C# struct, it can't change
Function binding:

{
var ____arg0 = @event.__Instance;
var __arg0 = new global::System.IntPtr(&____arg0);
var __ret = __Internal.SDL_WaitEvent(__arg0);
return __ret;
