Salut,

Globalement :
La fonction store_profile sauvegarde des données dans le registre (Aide sur les fonctions du registre). Ces données proviennent d'une structure network_data de type Network_config_data. L'instance et la structure sont probablement définies dans le .h.

La fonction read_profile fait l'opération inverse : registre ->  network_data.

Ensuite, tu as read_customize_profile et write_customize qui ont l'air tout à fait similaires.

Ensuite store_temp_data_for_dll, pareil, ressemble à store.

Et finalement clear_setting qui nettoie network_data.

Soit dit en passant, le code est très moche... Il y a certainement moyen de factoriser.

Donc globalement chargement/déchargement d'une structure dans le registre. Une structure en rapport avec le réseaux manifestement. Peut être pour le 802.1X si on en croit les commentaires.
