NAME

       libgvc - Graphviz context library

SYNOPSIS

       #include <graphviz/gvc.h>

       /* set up a graphviz context */
       extern GVC_t *gvNEWcontext(char **info, char *user);
       extern char *gvUsername(void);

       /*  set up a graphviz context ‐ alternative */
       /*     (wraps the above two functions using info built into libgvc) */
       extern GVC_t *gvContext(void);

       /* parse command line args ‐ minimally argv[0] sets layout engine */
       extern int gvParseArgs(GVC_t *gvc, int argc, char **argv);
       extern graph_t *gvNextInputGraph(GVC_t *gvc);

       /* Compute a layout using a specified engine */
       extern int gvLayout(GVC_t *gvc, graph_t *g, char *engine);

       /* Compute a layout using layout engine from command line args */
       extern int gvLayoutJobs(GVC_t *gvc, graph_t *g);

       /* Render layout into string attributes of the graph */
       extern void attach_attrs(graph_t *g);

       /* Parse an html string */
       extern char *agstrdup_html(char *s);
       extern int aghtmlstr(char *s);

       /* Render layout in a specified format to an open FILE */
       extern int gvRender(GVC_t *gvc, graph_t *g, char *format, FILE *out);

       /* Render layout in a specified format to an open FILE */
       extern int gvRenderFilename(GVC_t *gvc, graph_t *g, char *format, char *filename);

       /* Render layout according to -T and -o options found by gvParseArgs */
       extern int gvRenderJobs(GVC_t *gvc, graph_t *g);

       /* Clean up layout data structures ‐ layouts are not nestable (yet) */
       extern int gvFreeLayout(GVC_t *gvc, graph_t *g);

       /* Clean up graphviz context */
       extern int gvFreeContext(GVC_t *gvc);

DESCRIPTION

       libgvc  provides  a  context for applications wishing to manipulate and render graphs.  It
       provides a command line parsing,  common  rendering  code,  and  a  plugin  mechanism  for
       renderers.
