In a multithread task, sigset(SIGINT, SIG_DFL) is called. then one thread
sends SIGINT through pthread_kill() to the other thread.
Why the receiving thread is not terminated? Thanks a lot,
The receiving thread got EINTR if it is in read() system call since read()
returns -1.
What if recieving thread in an empty while loop.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I experienced the same problem!! And the pthread_kill just terminated
the program when I send SIGTERM. if I use SIGKILL, pthread_kill kill.
The other thing I hate is that it doesn't give you any error!
I switch to pthread_cancel. It's said it's not a good way to use.
But at lease it seems to work for my hw.

I mean POSIX thread. pthread_kill seems to work for Solaris thread.
