How to display st_atime and st_mtime - c

Question

I want to display my two attributes from the structure stat
struct stat {
dev_t st_dev; /* ID of device containing file */
ino_t st_ino; /* inode number */
mode_t st_mode; /* protection */
nlink_t st_nlink; /* number of hard links */
uid_t st_uid; /* user ID of owner */
gid_t st_gid; /* group ID of owner */
dev_t st_rdev; /* device ID (if special file) */
off_t st_size; /* total size, in bytes */
blksize_t st_blksize; /* blocksize for file system I/O */
blkcnt_t st_blocks; /* number of 512B blocks allocated */
time_t st_atime; /* time of last access */
time_t st_mtime; /* time of last modification */
time_t st_ctime; /* time of last status change */
};
Here is my code that i try to display the last time access and the last time of last modification of folder/file
struct tm *time;
char buffer[200];
time = localtime(file_info.st_atime);
strftime(buffer, sizeof(buffer), "%d.%m.%Y %H:%M:%S", time);
printf("%s\n", buffer);
time = localtime(file_info.st_mtime);
strftime(buffer, sizeof(buffer), "%d.%m.%Y %H:%M:%S", time);
printf("%s\n", buffer);
I want to display like human readble time and date like 15.03.1952 23:11:34 of a folder/file info that has been last modifed or access in linux

Answer 1

This deviates a bit from your code in terms of style, but perhaps it's helpful?
#include <time.h>
#include <stdio.h>
#include <sys/stat.h>
#include <stdlib.h>
char* formatdate(char* str, time_t val)
{
strftime(str, 36, "%d.%m.%Y %H:%M:%S", localtime(&val));
return str;
}
int main()
{
int errno;
const char* filename;
filename = "stat.c";
errno = 0;
struct stat *file_info = malloc(sizeof(struct stat));
if (lstat(filename, file_info) != 0) {
perror("Error");
exit(1);
}
char date[36];
printf("Access: %s\n", formatdate(date, file_info->st_atime));
printf("Modify: %s\n", formatdate(date, file_info->st_mtime));
printf("Change: %s\n", formatdate(date, file_info->st_ctime));
free(file_info);
return 0;
}

Answer 2

char buffer[200];
printf("Access : %s\n", formatdate(buffer, file_info.st_atime));
printf("Modify : %s\n", formatdate(buffer, file_info.st_mtime));
printf("\n\n");
char *formatdate(char *buff, time_t val)
{
strftime(buff,200, "%d.%m.%Y %H:%M:%S", localtime(&val));
return buff;
}
And this is the answer that i was looking for thanks again.

Answer 3

Try this: printf("%s", asctime(localtime(&buffer.st_mtime)));
