GenGdl File via IDC

要生成gdl文件可以使用idc脚本，也可以使用sdk的相关函数，但是函数使用比较复杂，其实是俺自己都没搞清楚那个东东该咋玩。丢银啊。

相关的函数有两个：

// Generate a flow chart GDL file
// outfile - output file name. GDL extension will be used
// title - graph title
// ea1 - beginning of the area to flow chart
// ea2 - end of the area 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 GenFuncGdl(string outfile, string title, long ea1, long ea2, long flags);

和

// Generate a function call graph GDL file
// outfile - output file name. GDL extension will be used
// title - graph title
// ea1 - beginning of the area to flow chart
// ea2 - end of the area 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_GEN_GDL, CHART_WINGRAPH, CHART_NOLIBFUNCS

success GenCallGdl(string outfile, string title, long flags);

简单测试代码：

#include <ida.idc>
#include <idc.idc>

static main()
{
auto str_gdlpath;
str_gdlpath = GetIdbPath();
str_gdlpath = substr(str_gdlpath,0,strlen(str_gdlpath)-4)+".gdl";
GenCallGdl(str_gdlpath, "Call Gdl", CHART_WINGRAPH);
Message("Gdl file have been saved to %s",str_gdlpath);
}
