You need to install a progress callback.  Something like:

--8<---------------cut here---------------start------------->8---
static void
progress_cb (void *opaque, const char *what, int type, int current, int total)
{
  (void)opaque;
  (void)type;

  if (total)
    fprintf (stderr, "progress for '%s' %u%% (%d of %d)\n",
             nonnull (what),
             (unsigned)(((double)current / total) * 100), current, total);
  else
    fprintf (stderr, "progress for '%s' %d\n", nonnull(what), current);
  fflush (stderr);
}


main()
{
  gpgme_set_progress_cb (ctx, progress_cb, NULL);
}
--8<---------------cut here---------------end--------------->8---


See gpgme/tests/run-genkey.c for a test program.
