14 int (*callback)(picl_nodehdl_t nodeh, void *c_args));

18 The ptree_walk_tree_by_class() function visits all the nodes of the
19 subtree under the node specified by rooth. The PICL class name of the
20 visited node is compared with the class name specified by classname. If
21 the class names match, the callback function specified by callback is
22 called with the matching node handle and the argument provided in
23 c_args. If the class name specified in classname is NULL, then the
24 callback function is invoked for all the nodes.
25
26
27 The return value from the callback function is used to determine
28 whether to continue or terminate the tree walk. The callback function
29 returns PICL_WALK_CONTINUE or PICL_WALK_TERMINATE to continue or termi‐
30 nate the tree walk.
31
33 Upon successful completion, 0 is returned. On failure, a non-negative
34 integer is returned to indicate an error.
