{

pthread_create(&thread,NULL,thread_fun,&thread_arg);

}
thread_fun()
{
printf("inside function");
}

when i do the gdb

>gdb test
> b func1
>n
> thread created.
> info threads
> shows two threads.
> thread 2 (switched to 2nd thread)



I have tried: break filename:line number thread 2

After i have entered "continue".

program exited normally came

Then how to debug the thread_fun().
Please help me.

Hi

Well, have you simply tried to issue "break thread_fun"? And have you made you your program is compiled with debugging symbol included? It is "-g" in gcc in case you forgot it.
