How to get tid of kernel threads?

Hi, when I make a new program it gets a certain process id(PID), I can get this using getpid().

Then I create a thread which have a thread ID, inside the process, a TID., I can get this also, pthread_self() and also the TID is returned when a thread is created.

BUT, when the scheduler is scheduling it schedules threads, kernel threads. How do I get this TID? that is the kernel thread ID of the threads I create in my process? How to get it?


I'm working in Solaris and Linux.

What do you need it for?

What to do a user-space scheduler. That is I will have one daemon that other programs can register their threads to for scheduling.

Doesn't that really mean that you will have to "keep" all the threads yourself, or are you planning to use some sort of "suspend_thread()", "unsuspend_thread()" mechanism, and to do that you need the actual internal thread ID?

Perhaps you can find some information inside the pthreads library itself?

No, the threads will register to this daemon and then this daemon will change their priorities based upon the algorithm of choice. The daemon itself will have the highest priority and sleep at given intervals letting other threads run.
