Subject: [PATCH -tip 07/14] perf tools: Add for_each macros for strlist
Date: Tue, 15 Dec 2009 15:27:00 -0000 [thread overview]
Message-ID: <20091215153156.17436.49157.stgit@dhcp-100-2-132.bos.redhat.com> (raw)
In-Reply-To: <20091215153106.17436.66584.stgit@dhcp-100-2-132.bos.redhat.com>
Add for_each iteration macros for strlist. This patch
introduces strlist__for_each() and strlist__for_each_safe(),
both are similar to list_for_each() and list_for_each_safe().
