Protected Static Methods
static intmax_t	create (bool initial_state, bool manual_reset)
	Create named event wait handle with specified initial state and manual reset.
static void	destroy (intmax_t handle)
	Destroy named event wait handle with specified event wait handle handle.
static bool	set (intmax_t handle, bool &io_error)
	Sets the state of the event to signaled, allowing one or more waiting threads to proceed.
static bool	reset (intmax_t handle, bool &io_error)
	Sets the state of the event to nonsignaled, causing threads to block.
