Your all to printf also gives undefined behavior because you've mismatched the conversion and the type (though on many current systems it's irrelevant because long and int are the same size).

It instructs printf() to print the first nread characters from message, eliminating the requirement for a null terminator in message. anchor by nikosv (Chaplain) on Jan 05, 2008 at 21:51UTC open(FILE, "> &=".fileno (HANDLE)); [reply] Re^2: Open a file on a specific file descriptor?
