PARAMETERS

node
The handle to a devinfo node in a di_init(3DEVINFO) snapshot.


path
The handle to a path node in a snapshot.


minor
The handle to a minor node in a snapshot.


link
The handle to a link in a snapshot.


lnode
The handle to an lnode in a snapshot.


data
A pointer to caller-specific data.

DESCRIPTION

The di_node_private_set() function allows a caller to associate caller-
specific data pointed to by data with a devinfo node, thereby
facilitating traversal of devinfo nodes in the snapshot.


The di_node_private_get() function allows a caller to retrieve a data
pointer that was associated with a devinfo node obtained by a call to
di_node_private_set().


The di_path_private_set() function allows a caller to associate caller-
specific data pointed to by data with a devinfo path node, thereby
facilitating traversal of path nodes in the snapshot.


The di_path_private_get()function allows a caller to retrieve a data
pointer that was associated with a path node obtained by a call to
di_path_private_set().


The di_minor_private_set() function allows a caller to associate caller-
specific data pointed to by data with a minor node specified by minor,
thereby facilitating traversal of minor nodes in the snapshot.


The di_minor_private_get() function allows a caller to retrieve a data
pointer that was associated with a minor node obtained by a call to
di_minor_private_set().


The di_link_private_set() function allows a caller to associate caller-
specific data pointed to by data with a link, thereby facilitating
traversal of links in the snapshot.


The di_link_private_get() function allows a caller to retrieve a data
pointer that was associated with a link obtained by a call to
di_link_private_set().


The di_lnode_private_set() function allows a caller to associate caller-
specific data pointed to by data with an lnode specified by lnode,
thereby facilitating traversal of lnodes in the snapshot.


The di_lnode_private_get() function allows a caller to retrieve a data
pointer that was associated with an lnode by a call to
di_lnode_private_set().


These functions do not perform any type of locking. It is up to the
caller to satisfy any locking needs.

RETURN VALUES

The di_node_private_set(), di_path_private_set(), di_minor_private_set(),
di_link_private_set(), and di_lnode_private_set() functions do not return
values.


The di_node_private_get(), di_path_private_get(), di_minor_private_get(),
di_link_private_get(), and di_lnode_private_get() functions return a
pointer to caller-specific data that was initialized with their
corresponding *_set() function. If no caller-specific data was assigned
with a *_set() function, the results are undefined.

ERRORS

No errors are defined.
