From 441ea0ce91d9df7e653c7a9598a62f230cf808c0 Mon Sep 17 00:00:00 2001 From: Stefano Sabatini Date: Mon, 3 May 2010 21:56:21 +0000 Subject: Make av_strerror() print an error message mentioning the error code number if strerror_r() did not succeed for whatever reason. This avoids the need for the application to fill the string in case strerror_r() fails, for example because the error code is not known.
