NAME
       picl_walk_tree_by_class - walk subtree by class

SYNOPSIS
       cc [ flag... ] file... -lpicl [ library... ]
       #include <picl.h>

       int  picl_walk_tree_by_class(picl_nodehdl_t  rooth,  const  char  *classname,  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 subtree under the node specified by rooth. The PICL class  name  of  the
       visited	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 terminate 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       PICL_STALEHANDLE is returned if the handle is no longer valid.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 dae-
       mon was brought down and restarted. When this occurs a client must revalidate 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
