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

       #include <dirent.h>

       int closedir(DIR *_d_i_r_p);

DDEESSCCRRIIPPTTIIOONN
       The _c_l_o_s_e_d_i_r() function shall close the directory stream referred to by
       the argument _d_i_r_p.  Upon return, the value of _d_i_r_p may no longer point
       to an accessible object of the type DDIIRR.  If a file descriptor is used
       to implement type DDIIRR, that file descriptor shall be closed.

RREETTUURRNN VVAALLUUEE
       Upon successful completion, _c_l_o_s_e_d_i_r() shall return 0; otherwise, -1
       shall be returned and _e_r_r_n_o set to indicate the error.

EERRRROORRSS
       The _c_l_o_s_e_d_i_r() function may fail if:

       EEBBAADDFF  The _d_i_r_p argument does not refer to an open directory stream.

       EEIINNTTRR  The _c_l_o_s_e_d_i_r() function was interrupted by a signal.
