Directory entry information APIs allow you to work with the directory
entries for files and directories in hierarchical file systems. The directory
entry information APIs are:
Change Directory Entry Attributes (QHFCHGAT) changes the attributes of a specified directory entry for an existing file or directory.
Close Directory (QHFCLODR) closes a specified directory that was opened using the Open Directory (QHFOPNDR) API.
Open Directory (QHFOPNDR) opens the specified directory so its directory entries can be read.
Read Directory Entry (QHFRDDR) reads one or more directory entries from a directory opened with the Open Directory (QHFOPNDR) API.
