The function h1_format_htx_msg() can now be used to convert a valid HTX message in its H1 representation. No validity test is performed, the HTX message must be valid. Only trailers are silently ignored if the message is not chunked. In addition, the destination buffer must be empty. 1XX interim responses should be supported. But again, there is no validity tests.
