My suggestion would be to look at the getchar standard library call. 
However, you have still not said exactly what you are trying to 
accomplish. Do you want your program to respond to the keyboard 
regardless of where you are in your program or do you only need keyboard 
input at a specific time? How many characters will you need to trap? 
Will you need to process the keyboard input or only know that some key 
has been pressed?
