- * DESCRIPTION
- * Creates a device node
+ * IopCreateDeviceKeyPath
*
- * ARGUMENTS
- * ParentNode = Pointer to parent device node
- * PhysicalDeviceObject = Pointer to PDO for device object. Pass NULL
- * to have the root device node create one
- * (eg. for legacy drivers)
- * DeviceNode = Pointer to storage for created device node
+ * Creates a registry key
*
- * RETURN VALUE
- * Status
+ * Parameters
+ * RegistryPath
+ * Name of the key to be created.
+ * Handle
+ * Handle to the newly created key
+ *
+ * Remarks
+ * This method can create nested trees, so parent of RegistryPath can
+ * be not existant, and will be created if needed.
