NAME
       opendir - open a directory

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

       DIR *opendir(const char *name);

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.

RETURN VALUE
       The  opendir()  function returns a pointer to the directory stream.  On error, NULL
       is returned, and errno is set appropriately.

ERRORS
       EACCES Permission denied.

       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.

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