From 39f21fd9c1bcd7f085193e5310efa79c3c759acd Mon Sep 17 00:00:00 2001 From: "plai@redhat.com" Date: Thu, 21 Jun 2018 18:54:39 +0200 Subject: [PATCH 30/57] osdep: add wait.h compat macros RH-Author: plai@redhat.com Message-id: <1529607285-9942-5-git-send-email-plai@redhat.com> Patchwork-id: 80938 O-Subject: [RHEL7.6 PATCH BZ 1526645 04/10] osdep: add wait.h compat macros Bugzilla: 1526645 RH-Acked-by: Michael S. Tsirkin RH-Acked-by: Maxime Coquelin RH-Acked-by: Laurent Vivier From: "Michael S. Tsirkin" Man page for WCOREDUMP says: WCOREDUMP(wstatus) returns true if the child produced a core dump. This macro should be employed only if WIFSIGNALED returned true. This macro is not specified in POSIX.1-2001 and is not available on some UNIX implementations (e.g., AIX, SunOS). Therefore, enclose its use inside #ifdef WCOREDUMP ... #endif. Let's do exactly this. Signed-off-by: Michael S.
