 A simpler test case:
 
 #include <netinet/in.h>
 #include <resolv.h>
 
 int main (int argc, char *argv[]) {
     if (argc < 2) return 1;
     int ret = res_hnok(argv[1]);
     printf("%d\n", ret);
 }
 
 Usage:
 
 landonf:~> ./test-res_hnok gc._msdcs.example.org
 0
 
 landonf:~> ./test-res_hnok gc.msdcs.example.org
