[webkit-help] Help: how to implement CFRunLoop logic on Windows Webkit version 157099

[houzhe at sohu.com]

I am trying to add some CFRunLoop logic in WinLauncher.cpp on Windows Webkit version 157099. There always are exceptions raised. My codes look like this: // callback functionvoid tick(CFRunLoopTimerRef timer, void *info) {	Logger::Instance()->WriteLog("I am going to dump DOM tree now. Tick...");}extern "C" __declspec(dllexport) int WINAPI dllLauncherEntryPoint(HINSTANCE, HINSTANCE, LPTSTR, int nCmdShow){// no change until around following line// Main message loop:    __try {#if USE(CF)		// my codes start		CFRunLoopTimerContext ctx;					CFRunLoopTimerRef timer = 			CFRunLoopTimerCreate(NULL, 					 CFAbsoluteTimeGetCurrent() + 10.0,					 0, 					 0, 					 0, 					 tick,					 &ctx);		CFRunLoopAddTimer(CFRunLoopGetMain(), timer, kCFRunLoopCommonModes);		// my codes end#endif        while (GetMessage(&msg, 0, 0, 0)) {#if USE(CF)            CFRunLoopRunInMode(kCFRunLoopDefaultMode, 0, true);#endif            if (!TranslateAccelerator(msg.hwnd, hAccelTable, &msg)) {                TranslateMessage(&msg);                DispatchMessage(&msg);            }        }    } __except(createCrashReport(GetExceptionInformation()), EXCEPTION_EXECUTE_HANDLER) { }exit:    gPrintDelegate->Release();    // other codes without change}Everytime, when 'tick' function is called, there is an exception raised. As no debug information is in WebKitSystemInterface.lib, I cannot trace the program line by line either. Can anybody let me know how shall I implement the logic? Thanks, Zhe
