You can interface to C++ from C without too much trouble: doing things like,
apt_c_version.cc:
#include <apt-pkg/version.h>
extern "C" {
int versioncmp(char *left, char *right) {
return pkgVersionCompare(left, right);
}
}
and then using versioncmp("1.2-3", "0.3-5") as you would strcmp() from C.
You need to be a little cleverer at abstracting objects when you need
to pass them around, and use void*'s and such, but it's not too tricky.
(From my experience with just the versioncmp stuff, libapt's is *muchly*
preferable: it's significantly faster, and doesn't leave dangling chunks
of memory lying about)

I don't speak for anyone save myself. GPG encrypted mail preferred.
