How can i know thread name for PDH from thread id

I need to check context switches for thread. I'm writing function, that return context switches from thread id. I'm computing context switch counts using the PDH library. I can get the thread context switch count for all threads using this construction:

Status = PdhAddCounter(Query, resultBuffer, NULL, &Counter);

where resultBuffer is "Thread(_Total/_Total)\\Context Switches/sec"

What do I have to change (_Total/_Total)?

Some playing around with perfmon suggests that the format should be

Thread(<process name>/<thread id>)\\Context Switches/sec

The thread ID you already have; you can get the process name from the process ID using the answers to this question.
