SDL/test/testautomation_joystick.c
Sam Lantinga bcbf09acde Renamed SDL_AttachVirtualJoystickEx() to SDL_AttachVirtualJoystick() 
The shorthand version of this function didn't allow specifying a controller name, which seems pretty important. It seems like anyone actually implementing a virtual joystick is going to want to use some of the extended functionality.
