Hm … naja!

Just another undocumented and bad code snippet

Nur für diejenigen die sich auch mit Metakit befassen ein weiteres schlechtes Beispiel Code, kein schöner Code aber vielleicht hilft es jemandem. Es hat zumindest meinen Zweck erfüllt eine Akregator Datenbank auszulesen. Geholfen hat mir auch die cplusplus.com Referenz geholfen.
