Subject: Add RtlSecureZeroMemory to explicit_bzero() compile case
X-Git-Tag: php-7.3.0alpha1~539
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=ec0bcecee7b3b54e3b870ab254f5a4ee79feed3d;p=php

Add RtlSecureZeroMemory to explicit_bzero() compile case

just in case one would use the function directly. The use of
ZEND_SECURE_ZERO could be eliminated now, too. Or it can be
kept for BC.
