Thread: Pass

I have the following code:

Code:

void printdir( )
{
    DIR *dp;
    struct dirent *entry;
    struct stat statbuf;
    int depth = 0;
    char *dir = ".";

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

I want to call a funtion that performs stuff against each file, how would I pass the file name stored in entry->d_name?

I want to be able to tell another code chunk what the file is and too perform stuff on it

would fopen (entry->d_name, "rb") work?

Like this, the code still does not access directories inside the other

Code:

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

void printdir(char *dir, int depth)

{

    DIR *dp;

    struct dirent *entry;

    struct stat statbuf;

    if((dp = opendir(dir)) == NULL) {

        fprintf(stderr,"cannot open directory: %s\n", dir);

        return;

    }

    chdir(dir);

    while((entry = readdir(dp)) != NULL) {



        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);

}

/*  Now we move onto the main function.  */

int main(int argc, char* argv[])

{

    char *topdir, pwd[2]=".";

    if (argc != 2)

        topdir=pwd;

    else

        topdir=argv[1];

    printf("Directory scan of %s\n",topdir);

    printdir(topdir,0);

    printf("done.\n");

    exit(0);

}

Thank you for all your help

Your real problem is that you are trying to use data in statbuf (which you have declared)
to select out directories without ever filling the buffer with any data (use fstat)!
