Josh,

It is possible to use OOP in C, we've been doing it at our company for abou=
t 7 years.

Search the archives, I posted some details on our implementation, a few yea=
rs ago.

Basically, it boils down to (1) using naming conventions to emulate OOP, an=
d (2) using aggregation instead of inheritance.

You can quickly get in trouble if you try to emulate inheritance/method ove=
rloading in C. The good news is, you can reap the benefits of OOP without i=
t.
