+ * Prompt for keyboard input.
+ *
+ * If the function returns FALSE, then the prompt operation could not be
+ * initiated and the user supplied callback is called to indicate that the
+ * operation was not started (reason KeyboardCompletionFailed). This can be
+ * used to centralize all cleanup work in the callback function.
+ *
+ * If the function returns TRUE, then the operation was initiated successfully
+ * and the prompt callback is guaranteed to be called sometime in the future.
+ * Note that it is posssible for the completion callback to have been already
+ * called by the time the function returns TRUE. In this instance, the
+ * callback will eventually be called with KeyboardCompletionSuccess, unless
+ * the operation is aborted before then.
+ *
+ * If the function returns TRUE, then a SilcAsyncOperation context may be
+ * returned. If an async operation context is returned, then the operation has
+ * not been completed immediately, and may be canceled with a call to
+ * silc_async_abort(*async).
+ *
+ * Note that the SilcAsyncOperation object's lifetime is managed internally. A
+ * user may call silc_async_abort exactly once, after which it can never touch
+ * the async context again. Additionally, the async context may not be
+ * referenced after the user callback returns. The recommended way to handle
+ * the async operation context is to remove the reference to it when the user
+ * callback is called, either for an abort or regular completion. If the
+ * callback is called with a KeyboardCompletionFailed reason, then no async
+ * context object was allocated.
+ *
+ * If an abort is requested, then the user callback is called with reason code
+ * KeyboardCompletionAborted. In this case, the user should clean up all
+ * associated callback data and perform the handling expected in the abort case,
+ * such as the associated server connection going away while the operation was
+ * in progress.
+ *
+ * There can only be one keyboard redirect operation in progress. If a
+ * keyboard redirect operation is aborted while we are still waiting for data,
+ * then we abort all callbacks until that callback returns.
