+ * @param hwndParent    A handle to the top-level window to use for any user adapter that is
+ *                      related to non-device-specific actions (such as a select-device dialog
+ *                      box that uses the global class driver list). This handle is optional
+ *                      and can be NULL. If a specific top-level window is not required, set
+ *                      hwndParent to NULL.
+ *
+ * @param szDeviceDescription  A pointer to a NULL-terminated string that supplies the text
+ *                      description of the device. This pointer is optional and can be NULL.
+ *
+ * @param szHwId        A pointer to a NULL-terminated string that supplies the hardware id
+ *                      of the device (e.g. "root\\tap0901", "Wintun").
+ *
+ * @param pbRebootRequired  A pointer to a BOOL flag. If the device requires a system restart,
+ *                      this flag is set to TRUE. Otherwise, the flag is left unmodified. This
+ *                      allows the flag to be globally initialized to FALSE and reused for multiple
+ *                      adapter manipulations.
+ *
+ * @param pguidAdapter  A pointer to GUID that receives network adapter ID.
+ *
+ * @return ERROR_SUCCESS on success; Win32 error code otherwise
