Are you trying to instanciate C? You can't instanciate classes with
pure virtual functions. Either remove the '=0' from the method
declarations in class C and later provide a definition, or create a new
class D deriving from C which implements func1() and func2().

If you've got something to say, say it. I'm not about to click on an
unknown link.

I am sorry, there is a correction, I have another class D(which is
bidir_chan) which implements those functions of class C and is inturn
instantiated.

If you're still having a problem, then show the actual code you're referring
to. We can't help you resolve the problem if we're only going by a vague
description.
