From e18a033b921d0d79fa8278f853548e6125b93e0c Mon Sep 17 00:00:00 2001 From: Konstantin Ananyev Date: Tue, 31 Oct 2017 12:40:17 +0000 Subject: Integrate TLDK with NGINX Created a clone of nginx (from https://github.com/nginx/nginx) to demonstrate and benchmark TLDK library integrated with real world application. A new nginx module is created and and BSD socket-like API is implemented on top of native TLDK API. Note, that right now only minimalistic subset of socket-like API is provided: - accept - close - readv - recv - writev so only limited nginx functionality is available for a moment.
