Hello,

Following code is executed in program as super user . but it doesn't effective . what may be the reason?

struct rlimit rl;
rl.rlim_cur = 5000;
setrlimit (RLIMIT_NOFILE, &rl);

Try this instead and post the results

if(  setrlimit (RLIMIT_NOFILE, &rl) != 0) {
    printf("setrlimit failed with error %d", errno); 
    exit(1);
}

It doesn't shows any error. After executing this code where it will be changed ? ulimit -n doesn't showed the changed value.

thanks,
