UDisksThreadedJobFunc ()

gboolean
(*UDisksThreadedJobFunc) (UDisksThreadedJob *job,

                          gpointer user_data,
                          GError **error);

Job function that runs in a separate thread.

Long-running jobs should periodically check cancellable to see if they have been cancelled.

                         GCancellable *cancellable);

Creates a new UDisksThreadedJob instance.

The job is not started automatically! Use udisks_threaded_job_start() to start the job after “threaded-job-completed” or “completed” signals are connected (to get notified when the job is done). This is to prevent a race condition with the job_func finishing before the signals are connected in which case the signal handlers are never triggered.

udisks_threaded_job_start ()

void
udisks_threaded_job_start (UDisksThreadedJob *job);

Start the job . Connect to the “threaded-job-completed” or “completed” signals to get notified when the job is done.

task = g_task_new (job, udisks_base_job_get_cancellable (UDISKS_BASE_JOB (job)), job_complete_cb, NULL);

/* Only spawn the completed callback once the job func has finished, we don't support early return as there still might be some undergoing I/O. */ g_task_set_return_on_cancel (task, FALSE); g_task_run_in_thread (task, run_task_job); g_object_unref (task); }

/** udisks_threaded_job_run_sync: job : the job to run error : The GError set in case of failure

Run the job synchronously.

Connect to the “threaded-job-completed” or “completed” signals to get notified when the job is done.

udisks_threaded_job_run_sync ()

gboolean
udisks_threaded_job_run_sync (UDisksThreadedJob *job,
                              GError **error);

udisks_threaded_job_get_user_data ()

gpointer
udisks_threaded_job_get_user_data (UDisksThreadedJob *job);

Gets the user_data parameter that job was constructed with.

UDisksThreadedJob

typedef struct _UDisksThreadedJob UDisksThreadedJob;

The UDisksThreadedJob structure contains only private data and should only be accessed using the provided API.

The “job-func” property

  “job-func”                 gpointer

The UDisksThreadedJobFunc to use.

Owner: UDisksThreadedJob

Flags: Read / Write / Construct Only

The “user-data” property

  “user-data”                gpointer

User data for the UDisksThreadedJobFunc.

Owner: UDisksThreadedJob

Flags: Read / Write / Construct Only

The “user-data-free-func” property

  “user-data-free-func”      gpointer

Free function for user data for the UDisksThreadedJobFunc.

Owner: UDisksThreadedJob

Flags: Read / Write / Construct Only

The “threaded-job-completed” signal

gboolean
user_function (UDisksThreadedJob *job,
               gboolean           result,
               GError            *error,
               gpointer           user_data)

Emitted when the threaded job is complete.

The default implementation simply emits the “completed” signal with success set to TRUE if, and only if, error is NULL. Otherwise, message on that signal is set to a string describing error . You can avoid the default implementation by returning TRUE from your signal handler.

This signal is emitted in the

thread-default main loop

of the thread that job was created in.
