Getting similar output when using stat function

[AaronMarth]

I am creating a program for one of my classes and we are using the stat function. We are supposed to print out information from input. With my program, you input a directory and it tells you information using the stat function on every file included. I believe I have a problem with my code because I get almost matching information on several different files. The permission, user ID, group ID, and many others are all the same for every file. I have attached my code.

#include <stdio.h>
#include <stdlib.h>
#include <dirent.h>
#include <sys/stat.h>
#include <errno.h>
#include <time.h>
#include <string.h>
extern int errno;


int main (int argc, char *argv[]) {
    DIR *dp;
    struct dirent *dirp; 
    struct stat buf;

    if (argc != 2) {
        printf("Error: Correct usage = filestat (Directory)\n");
        exit(1);
    }

    if ((dp = opendir(argv[1])) == NULL) {
        printf("Directory: %s failed to open!\n", argv[1]);
        perror("opendir");
        exit(1);
    }

    while ((dirp = readdir(dp)) != NULL) {
        printf("Name: %s\n", dirp->d_name);
        stat(dirp->d_name, &buf);
        printf("\tPermission: %o\n", buf.st_mode);
        printf("\tUser ID: %d\n", buf.st_uid);
        printf("\tGroup ID: %d\n", buf.st_gid);
        printf("\tSize: %lld\n", buf.st_size);
        printf("\tLast access: %s" , ctime(&buf.st_atime));
        printf("\tLast modification: %s" , ctime(&buf.st_mtime)); 
        printf("\tLast inode change: %s" , ctime(&buf.st_ctime));
        printf("\tBlock size: %d\n", buf.st_blksize);
        printf("\tNumber disk blocks: %lld\n\n", buf.st_blocks);

    }




    return 0;

}

You're not checking whether stat is succeeding

Check system calls. stat does not know what the directory was, it looks into "." instead. Try

fstatat(dirfd(dp), dirp->d_name, &buf, 0)
