如何在OMNeT ++中创建消息（.msg）的子类？

Question

I'm wondering whether it's possible to create a subclass of a message declaration (file *.msg which extends cPacket, see OMNeT++ Simulation Library ). What I've tried so far is:

packet childPacket : parentPacket{...}

and

parentPacket childPacket {...}

which both can't be compiled by opp_msgc .

Thus, I haven't found a way so far to achieve this and I'm very thankful for any hints.

Cheers

The solution is really simple and most probably it just shows my lack of knowledge in c++ (I thought 'extend' was just used in java)...

Finally, I could achieve my goal described above by just typing

packet childPacket extends parentPacket{...}

Oh gosh, it's hot in herre...
