如何正确打印出文件最后修改时间

yby123

#include <stdio.h> #include <sys/types.h> #include <sys/stat.h> #include <unistd.h> #include <string.h> int main() { &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;char *filename="/etc/hello.c"; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;struct stat info; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;memset(&info, 0, sizeof(struct stat)); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;stat(filename, &info); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;printf("size: %d\n", info.st_size); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;printf("mtime:%d\n",info.st_mtime); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return 0; }

运行结果

[root@localhost code]# ./stat
size: 4
mtime:1242907708

如何打印出时间呢？

自己搞定

#include <stdio.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
#include <string.h>
#include <time.h>
int main()
{
        char *filename="/etc/hello.c";
        struct stat info;
        memset(&info, 0, sizeof(struct stat));
        stat(filename, &info);
        printf("size: %d\n", info.st_size);
        printf("mtime:%s\n",ctime(&info.st_mtime));
        return 0;
}

yeehya

#include <time.h>

       char *asctime(const struct tm *tm);
       char *asctime_r(const struct tm *tm, char *buf);

       char *ctime(const time_t *timep);
       char *ctime_r(const time_t *timep, char *buf);

       struct tm *gmtime(const time_t *timep);
       struct tm *gmtime_r(const time_t *timep, struct tm *result);

       struct tm *localtime(const time_t *timep);
       struct tm *localtime_r(const time_t *timep, struct tm *result);

       time_t mktime(struct tm *tm);
