<p>Return a pointer to a C string containing the challenge for <em>question</em> within <em>rctx</em> , or NULL if the question is not present in <em>rctx</em> . The structure of the question depends on the question name, but will always be printable UTF-8 text. The returned pointer is an alias, valid only as long as the lifetime of <em>rctx</em> , and should not be modified or freed by the caller.</p>
