Need help with directories & files

GoboFraggle · 04-07-2003, 02:46 PM

How can I programmatically get info about directories and files such as current directory or where is a file located? I am using C/C++ on a Mandrake 9.0 system. I haven't had any luck looking this up on my own so am forced to seek your kind assistance. Thanks

Programming language, Operating System? :)

I'm programming in C/C++ using KDev.3 on a Mandrake 9.0 system. Guess I forgot that important bit of info.

Here is an example on a directory print:

Code:

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

void printdir()
{
DIR *dp;
struct dirent *entry;
struct stat statbuf;

if ( (dp = opendir(dir)) == NULL)
{
     fprintf(stderr, "cannot open directory: %s\n", dir);
      return;
}

while ( (entry = readdir(dp)) != NULL)
{
      lstat(entry->d_name, &statbuf);
       if (S_ISDIR(statbuf.st_mode))
       {
               /* Found a directory, but ignore . and .. */
                if (strcmp(".", entry->d_name) == 0 ||
                         strcmp("..", entry->d_name) == 0)
                             continue;

                       printf("%*s%s/\n", depth, "", entry->d_name);
                       /* recurse at a new indent level */
                        printDir(entry->d_name, depth+4);
                }
                else
                        printf("%*s%s\n", depth, "", entry->d_name);
        }
}

chdir("..");
closedir(dp);

}

Look at man pages for opendir, readdir, chdir......
