CLOSEDIR(3P)               POSIX Programmer's Manual              CLOSEDIR(3P)



PROLOG
       This manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may dif-
       fer (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 indi-
       cate 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.


       The following sections are informative.

EXAMPLES

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


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


                  closedir(dir);
              ...
