Returns a C character string which is the title of node, or the empty string (rather than NULL) if node does not have a title.

This may be different from node's "name" (see GetNodeName_bn).

There is no restriction on the length of the title, or on what characters it might contain.

If you need the string to persist, make a copy of the string returned, since its contents may become invalid after further calls to Netica API. Do not try to directly modify or free the string returned.
