Subject: [PATCH v5 1/4] sockets: introduce set_socket_error()
Date: Thu, 22 Mar 2012 11:52:35 +0800	[thread overview]
Message-ID: <20120322035235.2431.88671.stgit@dhcp-8-167.nay.redhat.com> (raw)
In-Reply-To: <20120322035052.2431.4994.stgit@dhcp-8-167.nay.redhat.com>

Introduce set_socket_error() to set the errno, use
WSASetLastError() for win32.
Sometimes, clean work would rewrite errno in error path,
we can use this function to restore real errno.
