Question

I’m trying to get a file list excluding diretories like “.” and “..”.
I use the following code to do that:

   DIR *dir;   
   struct dirent *ent;

   dir = opendir(currentDir);

   if (dir != NULL)   
   {
      while ((ent = readdir (dir)) != NULL) 
      {

         if (ent->d_name == "." || ent->d_name == "..")
         {
            continue;
         }
      }
   }

But it doesn’t work.

Answer 1

You should be using strcmp to compare strings. Rather than this:

if (ent->d_name == ".")

you need this:

if (strcmp(ent->d_name, ".") == 0)

Your code is comparing the pointers directly, rather than comparing the content of the strings.

See the strcmp documentation for more information.
