# gen\_flow\_graph

```
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
