+ * Request that the server should attempt to accept the Opaque PRF

+ * The callback can inspect the client-provided data in the input
+ * parameters, and specify its own opaque prf input data in the output
+ * variable.  The function must return 0 on success, otherwise the
+ * handshake will be aborted.
