* @short_description: Interaction with the user during TLS operations.
* @include: gio/gio.h
*
* #GTlsInteraction provides a mechanism for the TLS connection and database
* code to interact with the user. It can be used to ask the user for passwords.
*
* To use a #GTlsInteraction with a TLS connection use
* g_tls_connection_set_interaction().
*
* Callers should instantiate a derived class that implements the various
* interaction methods to show the required dialogs.
*
* Callers should use the 'invoke' functions like
* g_tls_interaction_invoke_ask_password() to run interaction methods. These
* functions make sure that the interaction is invoked in the main loop
* and not in the current thread, if the current thread is not running the
* main loop.
*
* Derived classes can choose to implement whichever interactions methods they'd
* like to support by overriding those virtual methods in their class
* initialization function. Any interactions not implemented will return
* %G_TLS_INTERACTION_UNHANDLED. If a derived class implements an async method,
* it must also implement the corresponding finish method.
