Subject: [PATCH 6/8] Make hostname available to C Code
Date: Thu, 15 Aug 2013 09:28:59 +0200 [thread overview]
Message-ID: <1376551741-16438-7-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1376551741-16438-1-git-send-email-s.hauer@pengutronix.de>
The boards often have a sane default for the hostname. Provide a C
function for setting/getting it.
