keycode of log keys of MacOS

I need to figure out the key code of log keys of Mac(ctrl, shift etc) or need to know how to track this log key press event...

basically I am converting mac key codes to equivalent windows key code...how can I do this?

+ (unsigned int) winKeyValueForKey:(unsigned int) macKeyValue{
unsigned int mapTable[128];
mapTable[0] = 0;
mapTable[1] = 0;
mapTable[2] = 0;
mapTable[3] = 0;
mapTable[4] = 0;
mapTable[5] = 0;
mapTable[6] = 0;
mapTable[7] = 0;

Control, Shift, Command, and Option keys on OS X do not generate NSKeyDown/kCGEventKeyDown events. Instead, you can receive a NSFlagsChanged/kCGEventFlagsChanged event.

That is, "typically" if the user typed Option-T and you are scanning keyDown events, you will only see a "T" event, which includes the fact that the option key is "modifying" it.

If you want to get flagsChanged events, you can receive that with an event tap, or in an NSResponder somewhere. The flagsChanged event tells you the new collection of modifiers (shift/command/etc). In that case, it is helpful to store a local copy of the previous modifiers so you can see which particular key went down or up.
