Do you want to write a command line application in C or a GUI based one? If it is command line based, just use stdin or whatever you use to normally get keyboard input. If it's GUI based, either you can wait for keyboard events or the simpler way is to ask the user to place the cursor in a text field and then scan. Then collect the information form the text field.
