tracking keyboard press/release events

i'm coding a program that will need to keep track of when the user presses and releases a key on the keyboard. What methods could i use to keep track of these actions, is there some flag or other way to tell when the user releases a key. I plan on using ctime to keep track of the exact times but need something to alert me of the events.
thanks

look up kbhit() and getch()

while( kbhit() == 0);
int value = getch();

something like that .... But you should really be doing windows programming.

right, "events" are really not the way DOS works. Windows get's messages for keyboard presses. DOS is just too procedural for that.
