FWIW the above manual counting is what apt-rpm does as well, and note the
comment:
// iSize = rpmdbGetIteratorCount(RpmIter);
// This doesn't seem to work right now. Code in rpm (4.0.4, at least)
// returns a 0 from rpmdbGetIteratorCount() if rpmxxInitIterator() is
// called with RPMDBI_PACKAGES or with keyp == NULL. The algorithm
// below will be used until there's support for it.
iSize = 0;
rpmdbMatchIterator countIt;
countIt = rpmxxInitIterator(Handler, RPMDBI_PACKAGES, NULL, 0);
while(rpmdbNextIterator(countIt) != NULL)
iSize++;
rpmdbFreeIterator(countIt);
