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_call- back() 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 current node. DI_WALK_TERMINATE Terminate the walk immediately. ERRORS
The di_walk_node() function will fail if: EINVAL Invalid argument. ATTRIBUTES
