    SubjectStrange piece of code
    Date
    Hi, I was having a tour in the kernel sources and I found some codes
    that I can't understand why. Like this in ppp:

    int
    ppp_init (struct device *dev)
    {
    static int first_time = 1; <== define to 1
    int answer = 0;

    if (first_time) { <== check if is 1, why ? any special special reason?
    first_time = 0;
    answer = ppp_first_time();
    if (answer == 0)
    (void) register_symtab (&ppp_syms);
    }
    if (answer == 0)
    answer = -ENODEV;
    return answer;
    }

    I found many more codes like this in the source, I cant remeber where anymore.
