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 differ (con-
       sult 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.


       The following sections are informative.

EXAMPLES
   Closing a Directory Stream
       The following program fragment demonstrates how the closedir() function is used.


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


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


                  closedir(dir);
              ...
