Do you mean like this?

+It can be a file descriptor referring to a directory.  Such a descriptor
+can be created explicitly using the @code{open} function, with or
+without the @code{O_DIRECTORY} amd @code{O_PATH} flags.

And also mention that the file name argument must be non-empty in this
case?
