From ebd4173a953995ded884f9c871f063c966a5337e Mon Sep 17 00:00:00 2001 From: guoshichao Date: Sun, 19 Jan 2025 17:17:33 +0800 Subject: [PATCH] sys/wait: add WCOREDUMP defintion Add the WCOREDUMP() macro to sys/wait.h to indicate whether a terminated process produced a core dump. This resolves implicit declaration warnings in LTP kernel testcases and improves POSIX compliance.
