PROLOG

       This  manual  page  is part of the POSIX Programmer's Manual.  The Linux implementation of
       this interface may differ (consult the corresponding Linux  manual  page  for  details  of
       Linux behavior), or the interface may not be implemented on Linux.

NAME

       closedir — close a directory stream

SYNOPSIS

       #include <dirent.h>

       int closedir(DIR *dirp);

DESCRIPTION

       The closedir() function shall close the directory stream referred to by the argument dirp.
       Upon return, the value of dirp may no longer point to an accessible  object  of  the  type
       DIR.   If  a  file descriptor is used to implement type DIR, that file descriptor shall be
       closed.

RETURN VALUE

       Upon successful completion, closedir() shall return 0; otherwise, −1 shall be returned and
       errno set to indicate the error.

ERRORS

       The closedir() function may fail if:

       EBADF  The dirp argument does not refer to an open directory stream.

       EINTR  The closedir() function was interrupted by a signal.

           ...
               if ((dir = opendir (".")) == NULL) {
           ...
               }

               while ((dp = readdir (dir)) != NULL) {
           ...
               }

               closedir(dir);
