Right, but I don't think you understood the code.

It chose an arbitrary number of groups that should work for most people. 
In case it isn't enough, it should reallocate with a larger count. That's 
why getgrouplist is called twice.

I had understood that the program I gave you worked out-of-the-box. If it 
didn't, tell me. What is the value of "ng" in the test program after the 
first getgrouplist?
