FwupdPlugin.DeviceLocker.new
Description: Reference for FwupdPlugin.DeviceLocker.new

### Constructor

# FwupdPlugin DeviceLockernew

since: 1.0.0

#### Declaration [src]

    FuDeviceLocker*
    fu_device_locker_new (
      FuDevice* device,
      GError** error
    )

#### Description [src]

Opens the device for use. When the `FuDeviceLocker` is deallocated the device will be closed and any error will just be directed to the console. This object is typically called using `g_autoptr()` but the device can also be manually closed using g_clear_object().

The functions used for opening and closing the device are set automatically.

NOTE: If the `open_func` failed then the `close_func` will not be called.

Think of this object as the device ownership.

Available since: 1.0.0

#### Parameters

`device`

  Type: `FuDevice`

  A `FuDevice`.

  The data is owned by the caller of the function.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the constructor if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

#### Return value

Type: `FuDeviceLocker`

A device locker, or `NULL` if the `open_func` failed.

The caller of the function takes ownership of the data, and is responsible for freeing it.
