Sleep Function

I have this piece of code.

printf("Exiting .");
sleep(1);
printf(" .");
sleep(1);
printf(" .");
sleep(1);
printf(" .");
sleep(1);
printf(" .");


I want to produce some sort of animation but then it does not seem to work as expected in unix/linux. The code works fine on windows. How to make that work in unix/linux?

Ok then I guess you are not getting the format as you expect... (dot by dot)
if yes, then you need to either flush the buffers or turn off buffering

printf("Exiting .");
fflush(stdout);
sleep(1);
printf(" .");
fflush(stdout);
sleep(1);
printf(" .");
fflush(stdout);
sleep(1);
printf(" .");
fflush(stdout);
sleep(1);
printf(" .");
fflush(stdout);

on windows sleep is in milliseconds and on linux it is in seconds ...
use usleep or nanosleep to achieve what you want

I am aware of the differences b/w windows and linux and that's why I do a sleep(1). I am trying to do this animation
