Solution for Exercise 23-3

ex2303

#include <stdio.h>
#include <stdlib.h>
#include <dirent.h>
#include <time.h>
#include <sys/stat.h>

int main()
{
    DIR *folder;
    struct dirent *file;
    struct stat filestat;

    folder=opendir(".");
    if(folder==NULL)
    {
        puts("Unable to read directory");
        exit(1);
    }
    while(file = readdir(folder))
    {
        stat(file->d_name,&filestat);
        printf("%-14s %5ld %s",
            file->d_name,
            (long)filestat.st_size,
            ctime(&filestat.st_mtime));
    }
    closedir(folder);
    return(0);
}

Notes

* If you don't typecast the filestat.st_size variable at Line 24, then the compiler pukes out a warning error. The code still compiles and runs.

* You can change the width values at Line 22 if the output looks too cluttered.

* See the solution for Exercise 23-2 for inforamtion on any "suggest parentheses" warnings you may see.
