Method

FwupdPluginDeviceget_backend_parent_with_subsystem

Declaration [src]

FuDevice*
fu_device_get_backend_parent_with_subsystem (
  FuDevice* self,
  const gchar* subsystem,
  GError** error
)

Description [src]

Creates a device parent (of the correct type) using the current backend for a given device kind.

NOTE: The backend must implement FuBackendClass->get_device_parent for this method to work — for cases where the plugin has created both parent and child, and used fu_device_add_child(), using fu_device_get_parent() is probably more appropriate.

Available since:

2.0.0

Parameters

`subsystem`	`const gchar*`
	An optional device subsystem, e.g. “usb:usb_device”
	The argument can be `NULL`.
	The data is owned by the caller of the function.
	The value is a NUL terminated UTF-8 string.
`error`	`GError **`
	The return location for a `GError*`, or `NULL`.

Return value

Returns:	`FuDevice`
	A `FuDevice` or `NULL` if not found or unimplemented.
	The caller of the method takes ownership of the data, and is responsible for freeing it.
