Subject: [PATCH 1/2] stringlist: use seperately allocated string.
Date: Fri, 10 Jun 2011 08:57:52 +0200 [thread overview]
Message-ID: <1307689073-9559-2-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1307689073-9559-1-git-send-email-s.hauer@pengutronix.de>
Allocate the string in string list seperately instead of
embedding a zero length string into struct stringlist.
Besides looking cleaner this allows us to implement a
string_list_asprintf.
