    Window (from XCreateSimpleWindow) is a long.

    The GdkWindow is a structure and the info has not been filled in yet.

    look in /usr/include/gtk-2.0/gdk/gdkwindow.h at the _GdkWindowObject struct.

    Let me boot up my 7.04 in a vm here at work and see if I can find the package you need to install from synaptic...


    maybe manpages-dev????
    sorry, can't find the exact package
  13. Re: C Question. Keeping output in straight column

    TreeFinger, forgive me if you already know this, but are you familiar with the "man" command. man is the "online manual" pages... you should be able to "man printf" and see the format options......
  14. Re: C Question. Keeping output in straight column

    I seem to recall some compat problems across unices many years ago when formatting the int in printf... but either way, it works on my cygwin too! good job.
  15. Re: C Question. Keeping output in straight column

    Well, one way is to copy the int into a char * using sprintf and then printf with the format you want.
    I hope you don't mind that I modified your prog a little:

    Re: C Question. Average n Numbers

    One way you could do it is to set the while loop to run then test the input with an if statement and do a break



    #include <stdio.h>

    int main(int argc, char **argv)
    {
    float x = 0.0;

    Re: a newbie question with GTK

    I tried your code and it compiled and the program ran for me.

    You must be missing some package but I don't know for sure.

  20. Re: Strange command line argument behaviour

    What is the size of "options"?
    What happens if you use sprintf(options, "%s", argv[1]); instead of strcpy(options, argv[1])?

    Could you post a bit more of the code?

    When you installed did you get the -dev libs?

    Well, it appears that my fifth 'perfect number' is not perfect afterall :(
    should be 33550336

    solution: check if "(pow(2, n) - 1)" is prime :)

    output is now:
