yes, right. However GdkPixbufAnimation and its iter_advance() function

On the

right. I submitted a patch which adds _get_frame_count and 
_get_current_frame functions to GdkPixbufAnimation.

Maybe there are animations where the concept of "frame count" doesn't
make sense?

However, I've now another small conceptual problem now: consider the 
following code:

         printf("compiled against gdk-pixbuf %s\n", GDK_PIXBUF_VERSION);
         printf("linked against gdk-pixbuf %s\n\n", gdk_pixbuf_version);

if I dynamically link my program on my linux which has e.g. gdk-pixbuf 
version 2.10.3 installed, and then run that binary on another linux 
which has gdk-pixbuf 2.8 installed, will I get

compiled against gdk-pixbuf 2.10.3
linked against gdk-pixbuf 2.8.0

or rather:

compiled against gdk-pixbuf 2.10.3
linked against gdk-pixbuf 2.10.3


I think the first: i.e. gdk_pixbuf_version contains the version of the 
dynamically loaded library, but I just want to be sure...

According to the docs it should be the first: gdk_pixbuf_version is an
external variable which lives in the lib (so it should reflect the lib's
version) while GDK_PIXBUF_VERSION is a C preprocessor macro which gets
"burnt into" your code at compile time.
