The FolderDescFlags enumeration defines masks your application can use in the AddFolderDescriptor function and the FolderDesc structure to specify various attributes of a folder. All other flag bits are reserved for future use. The FolderDescFlags constants are supported under Mac OS 8 and later.
You may set any combination of the following bits:
enum {
kCreateFolderAtBoot = 0x00000002,
kFolderCreatedInvisible = 0x00000004,
kFolderCreatedNameLocked = 0x00000008
};
typedef UInt32 FolderDescFlags;
