The SIGPIPE signal is sent to a process when it attempts to write to a pipe without a process connected to the other end. SIGPOLL The SIGPOLL signal is sent when an event occurred on an explicitly watched file descriptor. [18] Using it effectively leads to making asynchronous I/O requests since the kernel will poll the descriptor in place of ...
In teleprinter systems, the sequence "NNNN", on a line by itself, is an end of message indicator. In several Morse code conventions, including amateur radio, the prosign AR (dit dah dit dah dit) means end of message.
