From 30b1fc5a9820c7d8db273afd0c87f093f2857f9f Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Tue, 15 Oct 2024 13:25:10 +0200 Subject: [PATCH] ui/console-vc: Silence warning about sprintf() on OpenBSD MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The linker on OpenBSD complains: ld: warning: console-vc.c:824 (../src/ui/console-vc.c:824)([...]): warning: sprintf() is often misused, please use snprintf() Using g_strdup_printf() is certainly better here, so let's switch to that function instead.
