DIR *opendir(const char *name); 

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 opendir() function returns a pointer to the directory stream or NULL if an error occurred.

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.

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