di_walk_node(3devinfo)

Device Information Library Functions                    di_walk_node(3DEVINFO)



NAME
       di_walk_node - traverse libdevinfo device nodes

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

       int di_walk_node(di_node_t root, uint_t flag, void *arg,
            int (*node_callback)(di_node_t node, void *arg));

DESCRIPTION
       The  di_walk_node()  function visits all nodes in the subtree rooted at
       root. For each node found, the caller-supplied function node_callback()
       is  invoked.  The  return value of node_callback() specifies subsequent
       walking behavior.

PARAMETERS
       arg     Pointer to caller-specific data.


       flag    Specifies walking order, either DI_WALK_CLDFIRST (depth  first)
               or  DI_WALK_SIBFIRST  (breadth  first). DI_WALK_CLDFIRST is the
               default.


       node    The node being visited.


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


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


       The node_callback() function can return one of the following:

       DI_WALK_CONTINUE      Continue walking.


       DI_WALK_PRUNESIB      Continue  walking,  but  skip  siblings and their
                             child nodes.


       DI_WALK_PRUNECHILD    Continue walking, but skip subtree rooted at cur‐
                             rent node.


       DI_WALK_TERMINATE     Terminate the walk immediately.


ERRORS
       The di_walk_node() function will fail if:

       EINVAL    Invalid argument.
