recursion with segmentation fault

[q7h5]

To the recursion part, i got a segmentation fault. Can some one help me out?

int main(argc,argv)
      int argc;
      char **argv;
      {
          DIR *dhandle;
          struct dirent *entry3;
          unsigned char done = 0;
          char path[255];
    
          if (argc !=2)   sprintf(path,".");
          else            strcpy(path,argv[1]);
    
         dhandle=opendir(path);
              for (entry3=readdir(dhandle);entry3!=NULL;entry3=readdir(dhandle))
                printfDetails(entry3->d_name);
          rewinddir(dhandle);
          recursive(dhandle);
         closedir(dhandle);
      }
    
      recursive(d)
     DIR *d; {
      
      int exists;
      struct stat statbuf;
      struct dirent  *entry;
    
      for (entry=readdir(d);entry!=NULL;)
         {                                                      
           exists=stat(entry->d_name,&statbuf);
           if ((exists>=0)&&(S_ISREG(statbuf.st_mode)))
               printf("%20s\n",entry->d_name);
           else if ((exists>=0)&&(S_ISDIR(statbuf.st_mode))&&(entry->d_name[0]!='.')
)
              {
                d=opendir(entry->d_name);
               recursive (d);
              }
      else /* bypass the hidden files and . and .. */;
      }
      }

Rough guess, because your code is horribly formatted, and its hard to tell what's going on.
But your for loop in main() is only doing one statement


> int main(argc,argv)
> int argc;
> char **argv;
Get a better compiler, or a better book.
This style of C became out-dated 15 years ago.

You've also got some issues with your brackets. You need to include all of your main () stuff in brackets. ex

int main()
{
      blah blah blah
      return(0);
}

Not to mention, that like Salem said, this code is increadibly hard to read due to the format you wrote it in.
