Nginx C API: Traversing the configuration tree

Sorry, looks like I overlooked something in the API! It is possible to have a location-specific postconfiguration-hook: the last field of nginx_command_t. My bad!

I use the postconfiguration-hook in ngx_http_module_t and would like this hook to traverse over all locations that have been enabled in my module in order to initialise some state and set up some (database) connections. Does anybody know how to traverse the locations when given the root ngx_conf_t? I’ve found ngx_http_location_tree_node_t but I’ve failed to decipher how exactly it works. Besides that, is this the right way to do so, or is there some clever location-specific postconfiguration-hook that I’m missing?
