Implemented Interfaces

MMModem3gppUssd implements GDBusInterface, GInitable, GAsyncInitable and MmGdbusModem3gppUssd.

Description

The MMModem3gppUssd is an object providing access to the methods, signals and properties of the 3GPP USSD interface.

This interface is only exposed when the 3GPP modem is known to handle USSD operations.

Functions

mm_modem_3gpp_ussd_get_path ()

const gchar *
mm_modem_3gpp_ussd_get_path (MMModem3gppUssd *self);

Gets the DBus path of the MMObject which implements this interface.

Parameters

self

A MMModem3gppUssd.

Returns

The DBus path of the MMObject object.

[transfer none]

mm_modem_3gpp_ussd_dup_path ()

gchar *
mm_modem_3gpp_ussd_dup_path (MMModem3gppUssd *self);

Gets a copy of the DBus path of the MMObject object which implements this interface.

Parameters

self

A MMModem3gppUssd.

Returns

The DBus path of the MMObject. The returned value should be freed with g_free().

[transfer full]

mm_modem_3gpp_ussd_get_state ()

MMModem3gppUssdSessionState
mm_modem_3gpp_ussd_get_state (MMModem3gppUssd *self);

Get the state of the ongoing USSD session, if any.

Parameters

self

A MMModem.

Returns

A MMModem3gppUssdSessionState value, specifying the current state.

mm_modem_3gpp_ussd_get_network_request ()

const gchar *
mm_modem_3gpp_ussd_get_network_request
                               (MMModem3gppUssd *self);

Gets any pending network-initiated request.

The returned value is only valid until the property changes so it is only safe to use this function on the thread where self was constructed. Use mm_modem_3gpp_ussd_dup_network_request() if on another thread.

Parameters

self

A MMModem3gppUssd.

Returns

The network request, or NULL if none available.

[transfer none]

Gets a copy of any pending network-initiated request.

Parameters

self

A MMModem3gppUssd.

Returns

The network request, or NULL if none available. The returned value should be freed with g_free().

[transfer full]

mm_modem_3gpp_ussd_initiate ()

void
mm_modem_3gpp_ussd_initiate (MMModem3gppUssd *self,
                             const gchar *command,
                             GCancellable *cancellable,
                             GAsyncReadyCallback callback,
                             gpointer user_data);

Asynchronously sends a USSD command string to the network initiating a USSD session.

When the request is handled by the network, the method returns the response or an appropriate error. The network may be awaiting further response from the ME after returning from this method and no new command.

When the operation is finished, callback will be invoked in the thread-default main loop of the thread you are calling this method from. You can then call mm_modem_3gpp_ussd_initiate_finish() to get the result of the operation.

See mm_modem_3gpp_ussd_initiate_sync() for the synchronous, blocking version of this method.

Parameters

self	A MMModem3gppUssd.
command	The command to start the USSD session with.
cancellable	A GCancellable or `NULL`.	[allow-none]
callback	A GAsyncReadyCallback to call when the request is satisfied or `NULL`.
user_data	User data to pass to `callback` .

mm_modem_3gpp_ussd_initiate_finish ()

gchar *
mm_modem_3gpp_ussd_initiate_finish (MMModem3gppUssd *self,
                                    GAsyncResult *res,
                                    GError **error);

Finishes an operation started with mm_modem_3gpp_ussd_initiate().

Parameters

self	A MMModem3gppUssd.
res	The GAsyncResult obtained from the GAsyncReadyCallback passed to `mm_modem_3gpp_ussd_initiate()`.
error	Return location for error or `NULL`.

Returns

The response from the network, if any. The returned value should be freed with g_free().

mm_modem_3gpp_ussd_initiate_sync ()

gchar *
mm_modem_3gpp_ussd_initiate_sync (MMModem3gppUssd *self,
                                  const gchar *command,
                                  GCancellable *cancellable,
                                  GError **error);

Synchronously sends a USSD command string to the network initiating a USSD session.

The calling thread is blocked until a reply is received. See mm_modem_3gpp_ussd_initiate() for the asynchronous version of this method.

Parameters

self	A MMModem3gppUssd.
command	The command to start the USSD session with.
cancellable	A GCancellable or `NULL`.	[allow-none]
error	Return location for error or `NULL`.

                            GAsyncReadyCallback callback,
                            gpointer user_data);

Asynchronously responds to a USSD request that is either initiated by the mobile network, or that is awaiting further input after a previous call to mm_modem_3gpp_ussd_initiate().

When the operation is finished, callback will be invoked in the thread-default main loop of the thread you are calling this method from. You can then call mm_modem_3gpp_ussd_respond_finish() to get the result of the operation.

See mm_modem_3gpp_ussd_respond_sync() for the synchronous, blocking version of this method.
