Please, can someone help me. I DONT KNOW MORE WHAT I NEED TO DO. MY APPLICATION: - I have a application the have two others Threads (using pthread) belong the main() function running at same time. - Each one of both threads manipulates an individual SOCKET. - main() wait both theads to finish trying to lock a mutex already locked by threads, allowing application to finish only when two threads finished first. - main() handles signals like SIGTERM, and others. MY PROBLEM: 1) When my peer disconnects, my application (its threads) will be at some time trying to select(), send() or recv() the sockets. 2) I ve noted that select() cannot detect socket shutdown()/closing from peer, always returning OK and leaving in FD the socket originally being tested by select(). 3) After the wrong response from select() (we need to remember that the sockets was closed by peer above), my threads will try to send() and/or recv() the sockets, but exactly in this point, someone sends SIGTERM (15) that is handled by application, rather than, returning normal errors. 4) My application requests the theads to stop, flaging a specific variable, tested by threads. 5) When threads exit, main() function gain lock to the mutex, ending the application. Well, can be seeing above (item 3) that my application is being terminated without to detect that socket was closed by peer. My application think that the operation system sended a signal to it. (IT'S WRONG !) PLEASE ! I need help.
