    That's about the C api.

    I have a need to find out if a mysql connection is healthy or not,
    that is, is the server still up and able to serve queries, or not.

    How would I do it?

    mysql_error returns a lot of codes and it is unclear which ones are
    the ones to look for.

    mysql_ping() seems to be useful for this sort of thing, assuming
    the connection is not currently in use with a query. If you've
    timed out it will reconnect. Or, give it some kind of trivial query
    that proves you have access to the tables you need, e.g. DESCRIBE
    tablename or SELECT * FROM tablename LIMIT 1 .
