Subject: [PATCH v4 10/15] Improve the mingw getaddrinfo stub to handle more use cases
Date: Mon, 11 Oct 2010 23:50:24 +0200	[thread overview]
Message-ID: <1286833829-5116-11-git-send-email-kusmabite@gmail.com> (raw)
In-Reply-To: <1286833829-5116-1-git-send-email-kusmabite@gmail.com>

From: Martin Storsjö <martin@martin.st>

Allow the node parameter to be null, which is used for getting
the default bind address.

Also allow the hints parameter to be null, to improve standard
conformance of the stub implementation a little.

Signed-off-by: Martin Storsjo <martin@martin.st>
