From 451bb210f81c10b60bf90403c9183be26beaaabf Mon Sep 17 00:00:00 2001 From: Christian Couder Date: Mon, 2 Feb 2009 06:12:58 +0100 Subject: parse-options: add new function "usage_msg_opt" This function can be used instead of "usage_with_options" when you want to print an error message before the usage string. It may be useful because: if (condition) usage_msg_opt("condition is false", usage, opts); is shorter than: if (condition) { fprintf(stderr, "condition is false\n\n"); usage_with_options(usage, opts); } and may be more consistent.
