From dac4af81e3cb0a3307d737812ec6a9d830eaf31d Mon Sep 17 00:00:00 2001 From: Laine Stump Date: Wed, 15 Feb 2023 03:24:30 -0500 Subject: add die() to log an error message and exit with a single call Almost all occurences of err() are either immediately followed by exit(EXIT_FAILURE), usage(argv[0]) (which itself then calls exit(EXIT_FAILURE), or that is what's done immediately after returning from the function that calls err(). Modify the errfn macro so that its instantiations can include exit(EXIT_FAILURE) at the end, and use that to create a new function die() that will log an error and then exit.
