What do you think happens? Why do you think that? Did you read the documentation (man pages) for pthread_join and pthread_cancel? Have you tried writing a test program to see what happens?
EDIT: This site is a pretty useful pthreads reference: https://computing.llnl.gov/tutorials/pthreads/.

You are.
>>... what happens to b ?
We need actual code to answer these questions.

pthread_join() is a cancellation point. So if thread b is attempting to join thread c, and is cancelled before thread c exits, then the join is aborted and some other thread will have to join thread c. If the thread is not joined its resources will not be released.
