No, but the use of the API will be very very similar.

Mostly me.

Can you be more precise. What function exactly? It has a return value
but it doesn't have a return value?

Maybe you could link to viewcvs, or just mention exact files and
functions.

I'm sure that libgnomeprint*mm will work just as well as libgnomeprint*,
though there's the theoeritcal possibility that we might have some small
bugs to fix in the wrapper. But the wrapping is simple so there's no
hidden magic.

I doubt that _anybody_ is really using libgnomeprint*mm at the moment.
And not many people are using the C API either. However, it obviously
works for gedit, gnumeric, evolution, etc.

We are all waiting for the perfect cairo-based printing API to arrive in
a future version of GTK+.
