is thread alive ?

[pthread]

Hi,

Is there a API in pthread to get the state of the thread on hp-ux ?

State of the thread I meant by what time the thread started, whether the
thread still exists.

I could find pstat_getlwp but it would take lwpid as the argument ? any
alternatives of converting a pthread_t to lwp willalso help ..

regards

Same as kill, checks but doesn't kill it: pthread_kill(thread, 0);

Hi Dennis,

Thanks for the reply.

But if the pthread_id gets reused then I have to use the
start time of the thread, is there an API to do that in
the pthread library ?

Thanks

In a simple case I tried, I didn't see any reuse of the thread id but I don't think that is guaranteed.

[pthread]

So we have to need an API from pthread right ?

pstat_getlwp returns a very good piece of information, is there any in the same manner of pthread.

You need to remember all of the threads you created and make sure you remove the ones that die.
