cdnode(4) Kernel Interfaces Manual cdnode(4)
NAME
cdnode - format of a CDFS cdnode
SYNOPSIS
DESCRIPTION
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 informa-
tion is included in the cdnode for a given file into the standard stat structure (see stat(2)). However, since a cdnode includes informa-
tion 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.
