Another point where you have to ignore SIGPIPE is concurrent code that handles multiple fds (say, like a web server). In this case you have to ignore the signal

Another point where you have to ignore SIGPIPE is concurrent code that handles multiple fds (say, like a web server). In this case you have to ignore the signal and process EPIPE correctly, because the signal is not associated with a particular fd so you cannot tell which one of them failed.
