Understand,  thank you.

Ok, I understand now. Thanks

Thanks for answer. Of course. It seems I misunderstand it before. And I need lock without timing.

It is possible to catch somehow that second process found some critical area locked?. For example:
if (is not lock){
 lock

}else{

 behave else ( ..otherFunc())

}

Because if I use lock without timing, other process will sleep on lock like classical mutex, yes, your answer is correct, thanks, but I would like to know even more, if it is possible to externally check if lock is locked without falling asleep with process that will use LOCK +(^A,^B,^C), please?
