NAME
       opendir, fdopendir - open a directory

SYNOPSIS
       #include <sys/types.h>
       #include <dirent.h>

       DIR *opendir(const char *name);
       DIR *fdopendir(int fd);

DESCRIPTION
       The  opendir()  function	 opens a directory stream corresponding to the
       directory name, and returns a pointer to	 the  directory	 stream.   The
       stream is positioned at the first entry in the directory.

       The  fdopendir()	 is like opendir(), but returns a directory stream for
       the directory referred to by the open file descriptor fd.  After a suc‐
       cessful	call  to fdopendir(), fd is used internally by the implementa‐
       tion, and should not otherwise be used by the application.

RETURN VALUE
       The opendir() and fdopendir() functions return a pointer to the	direc‐
       tory  stream.   On  error, NULL is returned, and errno is set appropri‐
       ately.

ERRORS
       EACCES Permission denied.

       EBADF  fd is not a valid file descriptor opened for reading.

       EMFILE Too many file descriptors in use by process.

       ENFILE Too many files are currently open in the system.

       ENOENT Directory does not exist, or name is an empty string.

       ENOMEM Insufficient memory to complete the operation.

       ENOTDIR
	      name is not a directory.

VERSIONS
       fdopendir() is available in glibc since version 2.4.

CONFORMING TO
       opendir() is present on SVr4, 4.3BSD, and  specified  in	 POSIX.1-2001.
       fdopendir() is specified in POSIX.1-2008.

NOTES
       The  underlying file descriptor of the directory stream can be obtained
       using dirfd(3).

       The opendir()  function	sets  the  close-on-exec  flag	for  the  file
       descriptor  underlying  the DIR *.  The fdopendir() function leaves the
       setting of the close-on-exec flag unchanged for	the  file  descriptor,
       fd.   POSIX.1-200x  leaves  it unspecified whether a successful call to
       fdopendir() will set the close-on-exec flag for	the  file  descriptor,
       fd.
