ptree_walk_tree_by_class(3PICLTREE)			  PICL Plug-In Library Functions		       ptree_walk_tree_by_class(3PICLTREE)

NAME

       ptree_walk_tree_by_class - walk subtree by class

SYNOPSIS

       cc [ flag... ] file... -lpicltree [ library... ]
       #include <picltree.h>

       int ptree_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  ptree_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, 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.

ERRORS

       PICL_NOTNODE	     Not a node

       PICL_INVALIDHANDLE    Invalid handle specified

       PICL_STALEHANDLE      Stale handle specified

       PICL_FAILURE	     General system failure
