From cdf0d6c32f5c6c7c3071d35fa770eaf62fbad312 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Tue, 17 Feb 2009 21:36:43 +0100 Subject: src: remove old deprecated API This patch removes the first API version which was scheduled in 2007. That API had several major limitations that the new one solved. I don't know of any known existing client of this old API.
