VistaIO Version 1.2.14                            4 April 1995                               VistaIOReadEdges(3)

VistaIOReadEdges reads a Vista data file from an open stream, collects the top-level edge sets found, and
       returns the edge sets separately from the file's other contents.

       Besides the following, any of the diagnostics produced by VistaIOReadFile may be generated.

       ``No edges objects present in stream.''
              No edge sets were encountered in the specified stream.

VistaIOReadEdges  returns  the number of edge sets obtained, or 0 if an error is encountered. A vector of
       the edge sets is allocated and returned via edge_sets. Any other objects found in the file  are  returned
       as an attribute list via attributes.
