Optional callback function. If present, OllyDbg will call it on each pass of main loop. Here you can do all your periodical tasks. Don't assume that calls are equidistant; they aren't. Do not export this function unnecessarily, as this may negatively influence the overall speed!
void ODBG_Pluginmainloop(DEBUG_EVENT *debugevent);
Parameters:
debugevent - pointer to debug event received by call to Windows API function WaitForDebugEvent, or NULL if there was no event.
