function pointer to Opaque PRF extension server callback.
hook passed to callback function for passing application state.
Request that the server should attempt to accept the
Opaque PRF Input TLS extension. If the client requests the
extension, the provided callback cb will be invoked. The
callback must have the following prototype:
int callback (gnutls_session_t session, void *userdata, size_t oprfi_len, const unsigned char *in_oprfi, unsigned char *out_oprfi);
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.
