/******************************************************************************* * * FUNCTION: AcpiGetDevices * * PARAMETERS: HID - HID to search for. Can be NULL. * UserFunction - Called when a matching object is found * Context - Passed to user function * ReturnValue - Location where return value of * UserFunction is put if terminated early * * RETURNS Return value from the UserFunction if terminated early. * Otherwise, returns NULL. * * DESCRIPTION: Performs a modified depth-first walk of the namespace tree, * starting (and ending) at the object specified by StartHandle. * The UserFunction is called whenever an object of type * Device is found. If the user function returns * a non-zero value, the search is terminated immediately and this * value is returned to the caller. * * This is a wrapper for WalkNamespace, but the callback performs * additional filtering. Please see AcpiNsGetDeviceCallback. * ******************************************************************************/
