#include <stdio> #include <vistaio.h> #include <vistaio.h>
int VistaIOReadEdges (file, attributes, edge_sets)
FILE *file; VistaIOAttrList *attributes; VistaIOEdges (*edge_sets)[];
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.
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.
