From abdd677125f3a9e3082f8c5692203590fdb9b860 Mon Sep 17 00:00:00 2001 From: Rich Salz Date: Sun, 25 Jan 2015 21:07:20 -0500 Subject: [PATCH] Make OPENSSL_config truly ignore errors. Per discussion: should not exit. Should not print to stderr. Errors are ignored. Updated doc to reflect that, and the fact that this function is to be avoided.
