Functions
FileDirTypes	FileDirEntry_GetFileDirType (FileDirEntry *entry)
	Get the type of this FileDirEntry object as a value from the FileDirTypes enumeration.

long	FileDirEntry_GetLength (FileDirEntry *entry)
	Get the length of the given FileDirEntry object. For Files, this is a static value. For Directories, this is computed once from all the children of the directory and stored internally.

FileDirEntry *	FileDirEntry_GetChildren (FileDirEntry *entry)
	Retrieve a pointer to the first child of the given FileDirEntry object. If the entry does not support children or the entry has no children, returns a NULL pointer.

const char *	FileDirEntry_GetName (FileDirEntry *entry)
	Retrieve the name of the given FileDirEntry object.

time_t	FileDirEntry_GetWhenModified (FileDirEntry *entry)
	Retrieve the last modified time of the given FileDirEntry object.
