 SSL_CTX_set_cert_verify_callback() sets the verification callback function for
-B<ctx>. SSL objects, that are created from B<ctx> inherit the setting valid at
-the time, L<SSL_new(3)|SSL_new(3)> is called. B<arg> is currently ignored.

 =head1 NOTES
 
 Whenever a certificate is verified during a SSL/TLS handshake, a verification
 function is called. If the application does not explicitly specify a
 verification callback function, the built-in verification function is used.
-If a verification callback B<callback> is specified via

 =head1 BUGS
 
-It is possible to specify arguments to be passed to the verification callback.
-Currently they are however not passed but ignored.

-The B<callback> function is not specified via a prototype, so that no
