MySQL Connector/C++  8.0.6
MySQL connector library for C and C++ applications
MySQL Connector/C++ Documentation

MySQL Connector/C++ is a library for applications written in C or C++ that want to communicate with MySQL database servers. Version 8.0 of Connector/C++ implements new APIs which, on top of traditional SQL, give access to MySQL implementing a document store. For code written in C++ this is the new X DevAPI, which is the common MySQL API to access MySQL Document Store, also implemented by other MySQL connectors. Code written in plain C can use the XAPI – a new plain C API which offers functionality similar to X DevAPI.

More information:

Code that uses Connector/C++ 8.0 can communicate only with MySQL Server version 5.7 with X Plugin loaded into it.
