From b7cc9f82594a2d5fe12867c515d86d91ecedad8f Mon Sep 17 00:00:00 2001 From: =?utf8?q?Martin=20Storsj=C3=B6?= Date: Tue, 24 Nov 2009 00:55:12 +0200 Subject: [PATCH] Refactor winsock initialization into a separate function The winsock library must be initialized. Since gethostbyname() is the first function that calls into winsock, it was overridden to do the initialization. This refactoring helps the next patch, where other functions can be called earlier.
