Hi, I have a doubt about SSL_CTX 's app_verify_callback member variable. What for is this ? It seems that it this is set by using SSL_CTX_set_cert_verify_callback(SSL_CTX* ctx, int(*cb)(), char* arg), then cb() get called instead of X509_verify_cert(). Aslo what it looks that the int(*cb)() does not have any passed parameters, then how is it going to work. Any one has any ideas about it.
