3600 - Operating Systems - Lab-3 extra credit



Finish your mylab3.c program first, then you can work on this.

  1. Copy your 3600/2/xwin89.c program to 3600/3/myextra3.c


  2. Add some text similar to that above.
     XDrawString()


  3. Use signals to communicate between parent and child windows.
     SIGUSR1 maybe.


  4. The parent window will change the color of the child window.
     On key press or mouse click.


  5. You may ask Monique for help.


  6. Clues: You can call render() from a signal handler.
            You can store the window background color in a global variable.


Will be collected at 9:50am
