Constructor

FwupdPluginDeviceLockernew

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`	`FuDevice`
	A `FuDevice`.
	The data is owned by the caller of the function.
`error`	`GError **`
	The return location for a `GError*`, or `NULL`.

Return value

Returns:	`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.
