Verifying certificate was signed by a trusted Authority

[michael Dorrian]

I know SSL_CTX_load_verify_locations() loads the CAs you trust from a pem file that you store locally on your client machine but i cannot use this function as i dont want to read a pem file on the client side. I want to know if you can check to see if the server certificate presented was signed by a trusted certification authority or if its from a self signed CA. Is there any function in Openssl that can check for this?. I basically want to accomplish the same thing as when you connect to a secure server with your browser. If its a self signed certificate an extra dialog box appears warning you about this, if not this dialog box does not appear. I am not worried about the dialog boxes of course just a way of distinguishing between them. Is there a function in Openssl that does this?.
