B.3.1. Directory-based APIs within the File System API
The File System API contains APIs to read directory entries in a directory. It also contains
APIs to create, read, look up, and recursively remove files in a directory. Directory entries
are objects that describe either a file or subdirectory. A directory entry contains attrib-
utes defining the entry's status as a file or subdirectory, the pathname to the entry, and the
filesystem containing the entry.
Table B.38
lists the methods for the directory entry object. This object represents a direct-
ory entry in a filesystem. It includes methods for creating, reading, looking up, and recurs-
ively removing files and subdirectories in a directory.
