Function SetDebugHook

debug.go:163–174

SetDebugHook sets the debugging hook function. f is the hook function. mask specifies on which events the hook will be called: it is formed by a bitwise or of the constants MaskCall, MaskReturn, MaskLine, and MaskCount. The count argument is only meaningful when the mask includes MaskCount. For eac

(l *State, f Hook, mask byte, count int)

//
// A hook is disabled by setting mask to zero.
func SetDebugHook(l *State, f Hook, mask byte, count int) {
	if f == nil || mask == 0 {
		f, mask = nil, 0
	}
	if ci := l.callInfo; ci.isLua() {
		l.oldPC = ci.savedPC
	}
	l.hooker, l.baseHookCount = f, count
	l.resetHookCount()
	l.hookMask = mask
	l.internalHook = false
}

// DebugHook returns the current hook function.
func DebugHook(l *State) Hook { return l.hooker }
