 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.
