程序崩溃时生成DUMP文件

//首先，定义异常处理函数LONG WINAPI ExceptionFilter(LPEXCEPTION_POINTERS lpExceptionInfo) { typedef BOOL(WINAPI * MiniDumpWriteDumpT)( HANDLE, DWORD, HANDLE, MINIDUMP_TYPE, PMINIDUMP_EXCEPTION_INFORMATION, PMINIDUMP_USER_STREAM_INFORMATION, PMINIDUMP_CALLBACK_INFORMATION ); MiniDumpWriteDumpT pfnMiniDumpWriteDump = NULL; HMODULE hDbgHelp = LoadLibrary("DbgHelp.dll"); if (hDbgHelp) { pfnMiniDumpWriteDump = (MiniDumpWriteDumpT)GetProcAddress(hDbgHelp, "MiniDumpWriteDump"); } if (pfnMiniDumpWriteDump) { char szFileName[MAX_PATH] = { 0 }; ::GetModuleFileName(NULL, szFileName, _MAX_PATH); string str = szFileName; str = str.substr(0, str.length() - 4) + ".dmp"; HANDLE hFile = ::CreateFile(str.c_str(), GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL); if (hFile != INVALID_HANDLE_VALUE) { MINIDUMP_EXCEPTION_INFORMATION einfo; einfo.ThreadId = ::GetCurrentThreadId(); einfo.ExceptionPointers = lpExceptionInfo; einfo.ClientPointers = FALSE; pfnMiniDumpWriteDump(::GetCurrentProcess(), ::GetCurrentProcessId(), hFile, MiniDumpNormal, &einfo, NULL, NULL); ::CloseHandle(hFile); } return EXCEPTION_EXECUTE_HANDLER; } if (hDbgHelp != NULL) { FreeLibrary(hDbgHelp); } return EXCEPTION_EXECUTE_HANDLER; } //为程序设置异常处理函数 SetUnhandledExceptionFilter(ExceptionFilter);
