The man page for accept() is clear about this: ... and the socket is not marked as nonblocking meaning the parent listening socket. The "flags" argument of accept4() is purely for setting flags on the accepted new child socket, it has no influence whatsoever about the blocking of the accept() call or not. That behavior is determined in the context of the listening socket.
