Camel.Sasl.challenge

### Method

# Camel Saslchallenge

since: 3.0

#### Declaration [src]

    void
    camel_sasl_challenge (
      CamelSasl* sasl,
      GByteArray* token,
      gint io_priority,
      GCancellable* cancellable,
      GAsyncReadyCallback callback,
      gpointer user_data
    )

#### Description [src]

If `token` is `NULL`, asynchronously generate the initial SASL message to send to the server. (This will be `NULL` if the client doesn’t initiate the exchange.) Otherwise, `token` is a challenge from the server, and the asynchronous result is the response.

When the operation is finished, `callback` will be called. You can then call `camel_sasl_challenge_finish()` to get the result of the operation.

Available since: 3.0

This method completes asynchronously. Use `camel_sasl_challenge_finish()` inside the `GAsyncReadyCallback` to obtain the result of the operation.
