Method PushGoClosure

lua.go:959–971

PushGoClosure pushes a new Go closure onto the stack. When a Go function is created, it is possible to associate some values with it, thus creating a Go closure; these values are then accessible to the function whenever it is called. To associate values with a Go function, first these values shoul

func (l *State) PushGoClosure(function Function, upValueCount uint8) {
	if upValueCount == 0 {

	} else {
		n := int(upValueCount)

		l.checkElementCount(n)
		cl := &goClosure{function: function, upValues: make([]value, upValueCount)}
		l.top -= n
		copy(cl.upValues, l.stack[l.top:l.top+n])
		l.apiPush(cl)
	}

// PushThread pushes the thread l onto the stack.  It returns true if l is
// the main thread of its state.
