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 facili‐
tating 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 call‐
er-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 tra‐
versal 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 call‐
er-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_pri‐
vate_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_pri‐
vate_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_pri‐
vate_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.
