 This query shows that `stderr` is used somewhere in the program, but doesn't give us any more information. Using the query from the previous step, we can use the `astParent` construct to find out more about the surroundings of the `stderr` usage by moving up the hierarchy of the abstract syntax tree that is part of the Code Property Graph. Moving up one level in the AST hierarchy gives us an `fprintf` call:
