From: Pauli Date: Wed, 4 Sep 2019 09:27:08 +0000 (+1000) Subject: OSSL_PARAM_construct_utf8_string computes the string length. X-Git-Tag: openssl-3.0.0-alpha1~1505 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=7f588d20cd9ed2bb0ee2577a4523453964f532b0;p=oweals%2Fopenssl.git OSSL_PARAM_construct_utf8_string computes the string length. If the passed string length is zero, the function computes the string length from the passed string.
