Generate a flow chart GDL file
outfile - output file name. GDL extension will be used
title - graph title
ea1 - beginning of the range to flow chart
ea2 - end of the range to flow chart. if ea2 == BADADDR
then ea1 is treated as an address within a function.
That function will be flow charted.
flags - combination of CHART_... constants
success gen_flow_graph(string outfile, string title, long ea1, long ea2, long flags);
#define CHART_PRINT_NAMES 0x1000 // print labels for each block?
#define CHART_GEN_GDL 0x4000 // generate .gdl file (file extension is forced to .gdl)
#define CHART_WINGRAPH 0x8000 // call wingraph32 to display the graph
#define CHART_NOLIBFUNCS 0x0400 // don't include library functions in the graph
