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