readv(2) OSS System Calls Reference Manual
• IEEE Std 1003.1-2004, POSIX System Application Program Interface
• When a signal arrives during a call to a thread-aware readv() function, the thread-aware
readv() retries the I/O operation instead of returning the errno value [EINTR] with the
following exception. If the thread-aware fork() function is called by a signal handler
that is running on a thread performing a thread-aware readv() call, the thread-aware
readv() call in the child process returns [EINTR] to the application.
