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 (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.

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); ...

APPLICATION USAGE None.

RATIONALE None.

FUTURE DIRECTIONS None.
