Parent Thread Of Child Thread

Parent Thread Of Child Thread

Suppose a process creates some threads say threadC and threadD.
Later on each of these threads create new child threads say threadC1, threadC2, threadC3 etc. So a tree of threads will get created.
Is there any way to find out the parent thread of one such randomly created thread?

Actually when our application starts 70 threads gets created which is as per the requirement.
Later on as per the needs these 70 threads can create more threads.
So apart from these 70 threads a large number of other threads gets created(from these 70 threads) and destroyed randomly.
So imagine there is a tree of threads.
There is an issue coming up in one such randomly created thread.
On debugging the code we saw that the issue will be due to a value set by its
parent thread.
So we have to find the parent thread of this erroneus thread.

We are not able to get the parent thread id of this thread?

Will anybody let us know how to find the parent of such randomly created threads?

THREAD(3)								 1								 THREAD(3)

The Thread class

INTRODUCTION

	When the start method of a Thread is invoked, the run method code will be executed in separate Thread, asynchronously.

	After the run method is executed the Thread will exit immediately, it will be joined with the creating Thread at the appropriate time.

       Warning

	       Relying	on  the  engine to determine when a Thread should join may cause undesirable behaviour; the programmer should be explicit,
	      where possible.
