// WaitEvents is used for waiting for events, such as user input and window
// resize events. Upon calling this function, the calling thread will be put to
// sleep until any event appears in the event queue. When events are available,
// they will be processed just as they are processed by glfw.PollEvents.
//
// Note: It is guaranteed that glfw.WaitEvents will wake up on any event that
// can be processed by glfw.PollEvents. However, GLFW receives many events that
// are only processed internally and the function may behave differently on
// different systems. Do not make any assumptions about when or why
// glfw.WaitEvents will return.
func WaitEvents() { C.glfwWaitEvents() }
// WaitEvents puts the calling thread to sleep until at least one event has been
// received. Once one or more events have been recevied, it behaves as if
// PollEvents was called, i.e. the events are processed and the function then
// returns immediately. Processing events will cause the window and input
// callbacks associated with those events to be called.
//
// Since not all events are associated with callbacks, this function may return
// without a callback having been called even if you are monitoring all
// callbacks.
//
// This function may not be called from a callback.
//
// This function may only be called from the main thread.
