when you run the following command on shell--

stat -c %y filename

then it gives the then modification time similar to following...

year-day-month modification time...

when i used the stat() function in c program and tried to get the modification time then it gave me one big number...( probably in seconds..)

can i get the output similar to that one produced in shell script but using
stat() in c ?

A quick test program:

Code:

#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
#include <time.h>
#include <stdio.h>


int main(int argc, char *argv[])
{
  struct stat tmp;
  char buffer[50];
  
  stat(argv[1], &tmp);
  strftime(buffer, 50, "Modification time: %Y-%m-%d %T %z\n", localtime(&(tmp.st_mtime)));
  puts(buffer);
}
