The Vortex refInfo API, added in Texis version 8,
provides a set of functions for getting details of HTML references
(links). The API is implemented as a set of SQL functions which
return and manipulate in-memory objects, for maximum code flexibility
- the API is used almost exclusively in Vortex, not SQL. These
objects are obtained from a call to
<urlinfo allrefs refInfo>
(here) or the like, after a fetch.
