Subject: In x509.h rev. 1.35 2018/02/22 16:53:42, jsing@ provided
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=038d9bf665b473bc689ba390c4cd324b83a1474c;p=openbsd

In x509.h rev. 1.35 2018/02/22 16:53:42, jsing@ provided
X509_CRL_up_ref(3).  Since it is undocumented in OpenSSL,
write some documentation from scratch.  While here, also
correct the description of X509_CRL_free(3) and mention
X509_CRL_dup(3), too.
