                                      ...);

Launches a new job for `command_line_format` .

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

The returned object will be exported on the bus until the “completed” signal is emitted on the object. It is not valid to use the returned object after this signal fires.

#### Parameters

daemon | A UDisksDaemon. |
object | A UDisksObject to add to the job or `NULL`. | [allow-none]
job_operation | The operation for the job. |
job_started_by_uid | The user who started the job. |
cancellable | A GCancellable or `NULL`. |
run_as_uid | The uid_t to run the command as. |
run_as_euid | The effective uid_t to run the command as. |
input_string | A string to write to stdin of the spawned program or `NULL`. |
command_line_format | printf()-style format for the command line to spawn. |
... | Arguments for `command_line_format` . |

#### Returns

A UDisksSpawnedJob object. Do not free, the object belongs to `manager` .

job_operation | The operation for the job. |
job_started_by_uid | The user who started the job. |

### udisks_daemon_launch_threaded_job ()

    UDisksBaseJob *
    udisks_daemon_launch_threaded_job (UDisksDaemon *daemon,
                                       UDisksObject *object,
                                       const gchar *job_operation,
                                       uid_t job_started_by_uid,
                                       UDisksThreadedJobFunc job_func,
                                       gpointer user_data,
                                       GDestroyNotify user_data_free_func,
                                       GCancellable *cancellable);

Launches a new job by running `job_func` in a new dedicated thread.

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.

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

The returned object will be exported on the bus until the “completed” signal is emitted on the object. It is not valid to use the returned object after this signal fires.

#### Parameters

daemon | A UDisksDaemon. |
object | A UDisksObject to add to the job or `NULL`. | [allow-none]
job_operation | The operation for the job. |
job_started_by_uid | The user who started the job. |
job_func | The function to run in another thread. |
user_data | User data to pass to `job_func` . |
user_data_free_func | Function to free `user_data` with or `NULL`. |
cancellable | A GCancellable or `NULL`. |

#### Returns

A UDisksThreadedJob object. Do not free, the object belongs to `manager` .

### udisks_daemon_get_disable_modules ()

### udisks_daemon_get_force_load_modules ()

    gboolean
    udisks_daemon_get_force_load_modules (UDisksDaemon *daemon);

Gets `daemon` setting whether modules should be activated upon start.

#### Parameters

Gets the module manager used by `daemon` .

#### Parameters
