From 3b319885c4febb5f7ea9b5ab31c3395548ed6886 Mon Sep 17 00:00:00 2001 From: Zbigniew Jędrzejewski-Szmek Date: Sun, 16 Oct 2016 19:23:35 -0400 Subject: tree-wide: introduce free_and_replace helper It's a common pattern, so add a helper for it. A macro is necessary because a function that takes a pointer to a pointer would be type specific, similarly to cleanup functions. Seems better to use a macro. --- src/core/service.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) (limited to 'src/core/service.c') diff --git a/src/core/service.c b/src/core/service.c index 63045ede55..c949de9cbe 100644 --- a/src/core/service.c +++ b/src/core/service.c @@ -3088,9 +3088,7 @@ static void service_notify_message(Unit *u, pid_t pid, char **tags, FDSet *fds) if (!streq_ptr(s->status_text, t)) { - free(s->status_text); - s->status_text = t; - t = NULL; + free_and_replace(s->status_text, t); notify_dbus = true; } -- cgit v1.2.3-54-g00ecf
