From: Rich Salz Date: Wed, 26 Aug 2015 04:25:11 +0000 (-0400) Subject: Remove _locked memory functions. X-Git-Tag: OpenSSL_1_1_0-pre1~780 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=4c42ebd2f39ee30bf44cd016a3a838ab2efe8c08;p=oweals%2Fopenssl.git Remove _locked memory functions. Undocumented, unused, unnecessary (replaced by secure arena).
