Control interface nodes are identified by a node handle; some of these are defined in enum ctrl_node_type, here in libosmocore. However, applications defining own nodes may add own control nodes without having to extend the enum in libosmocore. For example, in the calling application, define an enum like "enum more_ctrl_nodes { CTRL_NODE_FOO = _LAST_CTRL_NODE, CTRL_NODE_BAR, _LAST_CTRL_NODE_EXTENDED }". In order to provide space for the additional control nodes, pass _LAST_CTRL_NODE_EXTENDED to the node_count parameter. Passing 0 is identical to passing _LAST_CTRL_NODE, i.e. to not define own control nodes apart from libosmocore ones.
