DI_WALK_LNODE 3DEVINFO "Mar 22, 2004"
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_callback() 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.
