NAME
       di_walk_lnode - traverse libdevinfo lnodes

SYNOPSIS
       cc [ flag... ] file... -ldevinfo [ library... ]
       #include <libdevinfo.h>

       int di_walk_lnode(di_node_t root, uint_t flag, void *arg, int (*lnode_callback)(di_lnode_t link, void *arg));

PARAMETERS
       root	       The handle to the root node of the subtree to visit.

       flag	       Specify 0. Reserved for future use.

       arg	       A pointer to caller-specific data.

       lnode_callback  The caller-supplied callback function.

DESCRIPTION
       The di_walk_lnode() function visits all nodes in the subtree rooted at root.  For each node found, the caller-supplied function lnode_call-
       back() is invoked for each lnode associated with that node.  The return value of lnode_callback()  specifies  subsequent  walking  behavior
       where that node is the specified endpoint of the link.

RETURN VALUES
       Upon successful completion, di_walk_lnode() returns 0.  Otherwise, -1 is returned and errno is set to indicate the error.

       The callback function lnode_callback() can return one of the following:

       DI_WALK_CONTINUE        Continue walking.

       DI_WALK_TERMINATE       Terminate the walk immediately.

ERRORS
       The di_walk_lnode() function will fail if:

       EINVAL	       An argument is invalid.
