The \fIclosedir\fP() function shall close the directory stream referred
to by the argument \fIdirp\fP. Upon return, the value
of \fIdirp\fP may no longer point to an accessible object of the type
\fBDIR\fP. If a file descriptor is used to implement type
\fBDIR\fP, that file descriptor shall be closed.
.SH RETURN VALUE

Upon successful completion, \fIclosedir\fP() shall return 0; otherwise,
-1 shall be returned and \fIerrno\fP set to indicate
the error.
