       cdnode - format of a CDFS cdnode

       This  entry describes the cdnode structure and related concepts for the
       CDFS file system.

       The CDFS file system does not have the concept  of  a  separate	entity
       called  an  inode.   The	 information normally found in an HFS inode is
       kept in a cdnode data structure.	 However, the  cdnode  data  structure
       does  not  reside  on the physical media, but instead is kept in kernel
       memory space only.  The cdnode information is used to uniquely identify
       a file.

       The information kept in the cdnode structure is obtained from two other
       data structures in the CDFS file system:

	      1.   Directory record for the file or directory, and

	      2.   Extended attribute record (XAR) for the file or  directory,
		   if one exists.

       Because	few  files  usually have XARs associated with them, the cdnode
       information most often consists only of attributes given by the	direc‐
       tory record for the file.

       Since  cdnodes  are  kept  in  kernel  memory,  they cannot be directly
       accessed by the user.  The system call attempts to map whatever	infor‐
       mation  is  included  in	 the cdnode for a given file into the standard
       stat structure (see stat(2)).  However, since a cdnode includes	infor‐
       mation  that  does not have corresponding fields in the stat structure,
       that information cannot be mapped and therefore cannot be accessed.  No
       method is provided to access an entire cdnode structure.

       stat(2), cdrom(4).
