--- Comment #2 from jannik.hoell...@gmail.com --- The example on the manpage includes the length since it's an example for the protocol/wire format. The 'out' variable itself is not in that format since it's only a single protocol, it can point to a part of in though. See: "The in, inlen parameters are a vector in protocol-list format. The value of the out, outlen vector should be set to the value of a single protocol selected from the in, inlen vector. The out buffer may point directly into in, or to a buffer that outlives the handshake" Also: "For the callback itself, out must be set to point to the selected protocol (which may be within in)" -- You are receiving this mail because: You are on the CC list for the bug. -- ## List details at https://lists.exim.org/mailman/listinfo/exim-dev Exim details at http://www.exim.org/ ##
