Neustrukturierung einer DLL

[EWeiss]

Hi

Wie einige vielleicht hier wissen habe ich die BassVis DLL geschrieben
Mein.. den User sein Problem ist nun das er für jede visualisierung WMP/WINAMP/SONIQUE

jede menge code schreiben muss da es für jede Visualisierung eigene dem Type angepaßte API gibt.

Das es für die Typen fast immer den gleichen aufruf gibt habe ich mir überlegt das ganze etwas zu kürzen.
Die Idee ist die Api so auszulegen das mit einen Aufruf jeder Typ angesprochen werden kann.

Bisher geht das so!
BASS_WINAMP_IsFree
BASS_WMP_IsFree
usw...

Wie würdet ihr vorgehen um den ganzen kram mit einem aufruf zu erledigen ohne zu viel am code zu ändern?
Es geht mir also um die Neustukturierung.

Die API sieht bisher so aus!
