Implemented Interfaces

MbimDevice implements GAsyncInitable.

Description

MbimDevice is a generic type in charge of controlling the access to the managed MBIM port.

A MbimDevice can only handle one single MBIM port.

Functions

mbim_device_new ()

void
mbim_device_new (GFile *file,
                 GCancellable *cancellable,
                 GAsyncReadyCallback callback,
                 gpointer user_data);

Asynchronously creates a MbimDevice object to manage file . When the operation is finished, callback will be invoked. You can then call mbim_device_new_finish() to get the result of the operation.

Parameters

file	a GFile.
cancellable	optional GCancellable object, NULL to ignore.
callback	a GAsyncReadyCallback to call when the initialization is finished.
user_data	the data to pass to callback function.

mbim_device_new_finish ()

mbim_device_new_finish (GAsyncResult *res,
                        GError **error);

Finishes an operation started with mbim_device_new().

Parameters

res	a GAsyncResult.
