Returns a list of the parents of node. Those are the nodes with a link going to node. If it has no parents then an empty list (rather than NULL) will be returned.

The order of the list is significant. Numbering each node in the list (starting from 0) provides a numbering for the links entering node, which is used by some other functions.

If there are several links from the same parent to node, then in the list returned that parent will be repeated once for each link.

To obtain the number of links entering node, use the length of the returned list.

If you need the list to persist, make a copy of the list returned (with DupNodeList_bn), since its contents may become invalid after further calls to Netica API (e.g., one that changes the links of a net, such as AddLink_bn). This is a list managed by Netica (declared const), so do not call any function to modify or free it (e.g., DeleteNodeList_bn).
