Let's go to the core question as it's near bed time Smilie

From a pure POSIX standpoint, if we want to get the "parent thread id" (the term "parent thread" is BTW is misnomer since POSIX states that all threads are peers), you need to keep track of the "thread's tree" yourself.

Now specifically, if you tell us which OS is (are) targeted, we may perhaps find an OS specific solution.

Cheers, Loïc

Killing a Child Thread

What is the best way for a parent to kill a child thread that has blocked on a command it cannot finish and will never read another line of its code? Will pthread_cancel() work with a thread that will never stop processing its current line of code? Thanks. (4 Replies)

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. CLASS SYNOPSIS
