Run the following program after creating the files foo and bar.What happens?
How can you set only one of the two time values with the utimesfunction?
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <unistd.h>
#include <stdio.h>
#include <stdlib.h>
#define RWRWRW(S_IRUSR|S_IWUSR|S_IRGRP|S_IWGRP|S_IROTH|S_IWOTH)
int main(int argc, char *argv[])
{
umask(0);
if (creat(“foo”, RWRWRW) < 0)
printf (“creat error for foo”);
umask(S_IRGRP | S_IWGRP | S_IROTH | S_IWOTH);
if (creat(“bar”, RWRWRW) < 0)
printf (“creat error for bar”);
exit(0);
}
