This optimization phase pops up an unexpected event on the standard event object processing.  It seems that frequent uses of SetEvent() API are not exactly processing-resources free. This is probably caused by some code overhead needed for a system object… During these evaluations, I … Continue reading A custom EVENT object for lighting fast thread synchronization »

This should allow you to easily track down some hidden/unnoticed problems. For example, suppose to have a C function like the below one: __MYOBJECTDATA * WINAPI MYOBJGetPtr (HANDLE hMyObject) { __MYOBJECTDATA *pObj; pObj = (__MYOBJECTDATA *) hMyObject; __try { if ((pObj != … Continue reading HOWTO Automatically Catch Problems While Debugging »
