    sleep function

    Im working on this project, and it works fine when I use the sleep function, the only thing is my teacher doesnt want us to use the sleep function, when i use the Wait(NULL) function, it causes the processes to freeze, so instead i was trying to use srand(time(NULL)), but that works sometimes and doesnt work other times. I was wondering if anyone knew any function that I could use instead of the sleep function to delay a process. Im also not allowed to use busy wait loops. My code is also on this site,

    and the part where I use srand(time(NULL)) is on line 00100.

    thanks!

    :blink: What?
    Code:
    if(counter > 0) { 
        for(int l=0;l<counter;l++) {
            srand(time(NULL));
            for(int j=rand(); j; j--);
        }
        wait(NULL);
    }
    What exactly are you trying to accomplish with this code?
    If I did your homework for you, then you might pass your class without learning how to write a program like this. Then you might graduate and get your degree without learning how to write a program like this. You might become a professional programmer without knowing how to write a program like this. Someday you might work on a project with me without knowing how to write a program like this. Then I would have to do you serious bodily harm. - Jack Klein

    Why do you have to wait in the first place?

    If your instructor doesn't want you to sleep.. they would you be able to wait for another even.. (such as a keystroke) before continuing..??

    Well, the other processes have to finish first and get their turn to receive the message, and then the input prompt should show up again to allow for user input again, so i was thinking the time delay would do it, but it only works some times.
