From d9c2fd793fe1e8c8fbfd7aec9af3482fa5f0dacc Mon Sep 17 00:00:00 2001 From: Andrew Clayton Date: Tue, 18 Mar 2025 05:09:31 +0000 Subject: Tag various character arrays with NXT_NONSTRING MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In Unit we have a number of character arrays which are intentionally not NUL terminated. With GCC 15 this static const char hex[16] = "0123456789ABCDEF"; will trigger a warning like $ gcc -Wextra -c nonstring.c nonstring.c: In function ‘hexit’: nonstring.c:9:37: warning: initializer-string for array of ‘char’ truncates NUL terminator but destination lacks ‘nonstring’ attribute (17 chars into 16 available) [-Wunterminated-string-initialization] 9 | static const char hex[16] = "0123456789ABCDEF"; | ^~~~~~~~~~~~~~~~~~ By adding NXT_NONSTRING like static const char hex[16] NXT_NONSTRING = "0123456789ABCDEF"; we no longer get the warning.
