SYNOPSIS
cc [ flag... ] file... -lpicl [ library... ]
#include <picl.h>
int picl_walk_tree_by_class(picl_nodehdl_t rooth, const char *class‐
name, void *c_args, int (*callback)(picl_nodehdl_t nodeh, void
*c_args));
DESCRIPTION
The picl_walk_tree_by_class() function visits all the nodes of the sub‐
tree under the node specified by rooth. The PICL class name of the vis‐
ited node is compared with the class name specified by classname. If
the class names match, then the callback function specified by callback
is called with the matching node handle and the argument provided in
c_args. If the class name specified in classname is NULL, then the
callback function is invoked for all the nodes.
The return value from the callback function is used to determine
whether to continue or terminate the tree walk. The callback function
returns PICL_WALK_CONTINUE or PICL_WALK_TERMINATE to continue or termi‐
nate the tree walk.
RETURN VALUES
Upon successful completion, 0 is returned. On failure, a non-negative
integer is returned to indicate an error.
PICL_STALEHANDLE is returned if the handle is no longer valid. This
occurs if the PICL tree was refreshed or reinitialized.
PICL_INVALIDHANDLE is returned if the specified handle never existed.
This error may be returned for a previously valid handle if the daemon
was brought down and restarted. When this occurs a client must revali‐
date any saved handles.
ERRORS
PICL_NOTINITIALIZED Session not initialized
PICL_NORESPONSE Daemon not responding
PICL_NOTNODE Not a node
PICL_INVALIDHANDLE Invalid handle specified
PICL_STALEHANDLE Stale handle specified
PICL_FAILURE General system failure
