Does gtk_ctree_find_by_row_data() search entire ctree?

[learfox furry ao net]

Does gtk_ctree_find_by_row_data() search the entire ctree (all
GtkCTreeNodes on the given ctree) if I pass the starting GtkCTreeNode
as NULL?

If not, then how do I check if a given GtkCTreeNode (by either the
GtkCTreeNode pointer or user set data pointer) is on the specified ctree?
