From 3f8f1c6ff24ee858eb5b0bf47ef6d4605299a87e Mon Sep 17 00:00:00 2001 From: Martin Storsjö Date: Fri, 24 Oct 2014 10:33:19 +0300 Subject: lavu: Provide fallbacks for gmtime_r and localtime_r MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This allows writing most code as if they always are is available. These are ok to use from other libraries even though it's not a public header, since they only provide an inline declaration, and doesn't add an actual dependency on lavu internals. (This can be considered more a build system compatibility fallback than a libavutil feature.)
