+ * @brief File containing network interface detection functions for Windows.
+ *
+ * The only public function of this module is #getAdapterInfos(OsAdapterInfo *,
+ * size_t *), other functions are either static or inline.
+ *
+ * Responsibility of this module is to fill OsAdapterInfo structures, in a predictable way (skip loopback/vpn interfaces)
