Author: kib Date: Thu Mar 30 04:57:26 2017 New Revision: 316213 URL: https://svnweb.freebsd.org/changeset/base/316213
Log: Implement the memset_s(3) function as specified by the C11 ISO/IEC 9899:2011 Appendix K 3.7.4.1. Other needed supporting types, defines and constraint_handler infrastructure is added as specified in the C11 spec.
