From f3c1a187fe2bc33f8423cd535d5045899699995b Mon Sep 17 00:00:00 2001 From: Lars Hjemli Date: Mon, 24 Mar 2008 00:51:19 +0100 Subject: Add struct cgit_page to cgit_context This struct is used when generating http headers, and as such is another small step towards the goal of the whole cleanup series; to invoke each page/view function with a function pointer.
