[hackers] [PATCH] dd: Use sigaction(2) to obviate select(2)

2017-09-10 Thread Eric Pruitt

By setting the SIGINT handler with sigaction(2), automatic retries of the splice(2) syscall can be disabled by not setting SA_RESTART. This makes it possible to use Ctrl+C even if the "if" operand refers to the controlling terminal. The SIGINT message has also been moved outside the signal handler
