PROLOG

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

NAME

12       closedir - close a directory stream
13

SYNOPSIS

15       #include <dirent.h>
16
17       int closedir(DIR *dirp);
18
19

DESCRIPTION

21       The closedir() function shall close the directory stream referred to by
22       the  argument  dirp. Upon return, the value of dirp may no longer point
23       to an accessible object of the type DIR. If a file descriptor  is  used
24       to implement type DIR, that file descriptor shall be closed.
25

RETURN VALUE

27       Upon  successful  completion,  closedir() shall return 0; otherwise, -1
28       shall be returned and errno set to indicate the error.
29

ERRORS

31       The closedir() function may fail if:
32
33       EBADF  The dirp argument does not refer to an open directory stream.
34
35       EINTR  The closedir() function was interrupted by a signal.
