The handle to the root node of the subtree to visit.
Specify 0. Reserved for future use.
Specify if the current node being visited should be the target or source of an link, either DI_LINK_TGT or DI_LINK_SRC
A pointer to caller-specific data.
The caller-supplied callback function.
The di_walk_link() function visits all nodes in the subtree rooted at root. For each node found, the caller-supplied function link_callback() is invoked for each link associated with that node where that node is the specified endpoint of the link. The return value of link_callback() specifies subsequent walking behavior. See RETURN VALUES.
Upon successful completion, di_walk_link() returns 0. Otherwise, -1 is returned and errno is set to indicate the error.
The callback function, link_callback(), can return one of the following: DI_WALK_CONTINUE
Continue walking.
Terminate the walk immediately.
The di_walk_link() function will fail if: EINVAL
An argument is invalid.
