PROLOG         top

       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         top

       closedir — close a directory stream

SYNOPSIS         top

       #include <dirent.h>

       int closedir(DIR *dirp);

DESCRIPTION         top

       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         top

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

ERRORS         top

       The closedir() function may fail if:

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

               struct dirent *dp;
           ...
               if ((dir = opendir (".")) == NULL) {
           ...
               }

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

               closedir(dir);
           ...
