callback function in a struct

Hi,

Can any one give me a basic example and requirement for
using a callback function in a structure?
Googled but could not find which I can appreciate.

Thanks.....

Re: callback function in a struct

A callback function in a structure is just a function pointer.

If you want good examples of that, look at the Linux kernel source,
it's full with them. It's useful for implementing a given API, a bit like
inheritance in object oriented languages.
