- * Funkcja przeprowadza połączenie HTTP przy połączeniu synchronicznym,
- * zwracając wynik w polach struktury \c gg_http, lub błąd, gdy sesja się
- * nie powiedzie.
- *
- * Przy połączeniu asynchronicznym, funkcja rozpoczyna połączenie, a dalsze
- * etapy będą przeprowadzane po wykryciu zmian (\c watch) na obserwowanym
- * deskryptorze (\c fd) i wywołaniu funkcji \c gg_http_watch_fd().
- *
- * Po zakończeniu, należy zwolnić strukturę za pomocą funkcji
- * \c gg_http_free(). Połączenie asynchroniczne można zatrzymać w każdej
- * chwili za pomocą \c gg_http_stop().
- *
- * \param hostname Adres serwera
- * \param port Port serwera
- * \param async Flaga asynchronicznego połączenia
- * \param method Metoda HTTP
- * \param path Ścieżka do zasobu (musi być poprzedzona znakiem '/')
- * \param header Nagłówek zapytania plus ewentualne dane dla POST
- *
- * \return Zaalokowana struktura \c gg_http lub NULL, jeśli wystąpił błąd.
