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.
The following sections are informative.
