From 28464179174d2c3d1c1bc124ba9c2519e08a5fc9 Mon Sep 17 00:00:00 2001 From: Michael Adam Date: Tue, 26 Feb 2008 13:24:54 +0100 Subject: libreplace: Add tests for connect and gethostbyname. Provide dummy replacements when a function isnt found. The functions are also searched for in certain libraries, and variables SOCKET_LIBS and NSL_LIBS are set accordingly. One purpose of this is to fix the getifaddrs tests on systems where e.g. the socket calls require special libs for linking.
