    How to use Sleep function?

    EDIT *Just worked out how to do this (include windows.h, sleep(tired*1), tired measured in miliseconds)* Feel free to close thread.


    I've been searching around on google on how to use this. I know i have to #include <unistd.h>, and my source code:

    Code:
    #include <unistd.h>
    #include <stdio.h>
    
    int main(void)
    {
        
        printf("I'll be back in 10 seconds...\n\n");
        sleep(10);
        printf("I'm back!");
        getchar();
        
        return(0);
    }
    The output just prints:
    Code:
    I'll be back in 10 seconds...
    
    I'm back!
    With no interval in between.

    Am I using this incorrectly?

    Thanks

    If you are using Windows, Sleep takes time in milliseconds.
    If you are using Linux, sleep takes time in seconds.
    Also note the case, because C is case sensitive!
    For Windows, Sleep is defined in Windows.h.

    Outside of your DOS world, your header file is meaningless.
