From: Jeremiah Mahler Date: Sun, 01 Jun 2014 18:10:13 GMT Subject: [PATCH v3 4/9] write_or_die.c: replace signal() with sigaction() Message-ID: In-Reply-To: From the signal(2) man page: The behavior of signal() varies across UNIX versions, and has also var‐ ied historically across different versions of Linux. Avoid its use: use sigaction(2) instead.
