Yes, you are incorrect. I am incrementing the pointer when I wanted to increment the value. Probably this is an artefact from rewriting the code a few times.

But indeed this has not been a problem since the function is not being called at all in the code, and it is not being exported.

So assuming that it is not very useful, I will drop loc_network_tree_count_networks and the callback function.

Thank you for helping to improve libloc. How does it run on Windows?

Best,
