VistaIOReadEdges - read a series of edge sets from a stream
#include <stdio> #include <vistaio.h> #include <vistaio.h> int VistaIOReadEdges (file, attributes, edge_sets) FILE *file; VistaIOAttrList *attributes; VistaIOEdges (*edge_sets);
file Specifies the open stream from which the edge sets should be read. attributes Returns a list of attributes read from the stream. edge_sets Returns a vector of pointers to edge sets read.
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.
VistaIOReadFile(3), VistaIOReadObjects(3), stdio(3), VistaIOEdges(3)
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.
