Question

C++ / C#

Which library for msgpack format with C++ implementation of pack_raw_body method?
Mentions that various programs use the pack_raw_body method from this library are available on the Internet. This can be seen in the source codes of many programs.
But all those libraries that I found that are in the distribution kit of my OS, that the one pointed to by the msgpack site - for some reason do not contain pack_raw_body.

Answer 1

It turns out that my OS uses too recent msgpack 1.3.0 The
necessary functions are only in the very ancient msgpack 0.5.7
Fortunately, the author of msgpack has kept those versions
