I have developed a time critical process (application program) run under Windows XP. I would like to let this process run with highest priority among the other processes which also run on Windows. We have tried to use Win 32 API function SetPriorityClass() and set process priority with REAL_TIME, but it is seems does not work. I don't know whether I miss some steps setting. Can all of you offer some suggestions or codes to solve my problem. Thanks!
