Method

FwupdPluginDeviceget_backend_parent_with_subsystem

since: 2.0.0

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

Type: 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 method.

The value is a NUL terminated UTF-8 string.

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 method 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: FuDevice

A FuDevice or NULL if not found or unimplemented.

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