usw....
Der aufmerksame Beobachter wird merken, dass es sich immer um doppelte deklarationen handelt.
Nun zur Frage:

Kann es sein, dass windows.h winsock.h einbindet?
Das würde ja heißen, dass wenn ich dann nochmal winsock2 einbinde, dass ich dann
doppelte deklarationen hätte.

Wenn das so ist, wie kann ich das verhindern und trotzdem winsock2 benurtzen??

Winsock würde dann ja eher in das allg. Forum passen
