Program to find Resource Limits of stack using setrlimit and getrlimit

#include"myHeader.h"
main()
{
struct rlimit v,new;
getrlimit(RLIMIT_STACK,&v);
new=v;
new.rlim_cur=2000;
setrlimit(RLIMIT_STACK,&new);
getrlimit(RLIMIT_STACK,&new);
printf("new resource current limit address=%lu \n new resource maximum limit=%lu\n",new.rlim_cur,new.rlim_max);
}

OutPut:

madan@madan-Lenovo-G570:~/madan/osconcepts$ cc ex2.c
madan@madan-Lenovo-G570:~/madan/osconcepts$ ./a.out
new resource current limit address=2000 
 new resource maximum limit=18446744073709551615
