[dxy <2354528200@xxxxxx>]

Hello,I am writing a program using dynisnt to avoid buffer overflow.I meet one trouble.Hope to get help from you.

                                if(category == Dyninst::InstructionAPI::c_CallInsn) {
                                    vector<BPatch_point *> callPoints;
                                    appImage->findPoints(addr, callPoints);
                        
                                    BPatch_function * fun1=callPoints[0]->getCalledFunction();
                                 }
I don't know why this didn't work. fun1==NULL.every time.
