       opendir, fdopendir - open a directory

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

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

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

	   Since glibc 2.10:
	       _XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
	   Before glibc 2.10:

       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() function is like opendir(), but returns a directory stream for the direc-
       tory referred to by the open file descriptor fd.  After a successful call to  fdopendir(),
       fd  is  used  internally  by  the  implementation, and should not otherwise be used by the

       The opendir() and fdopendir() functions return a pointer  to  the  directory  stream.   On
       error, NULL is returned, and errno is set appropriately.

       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.

	      name is not a directory.

       fdopendir() is available in glibc since version 2.4.

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

       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.
