How to bind an enum field in the c connector for a prepared statement ?

For a select statement (so in binding the result set) using a fixed sized char buffer and specifying the field type as MYSQL_TYPE_STRING works. But for an insert statement (so in binding the parameters) this does not work. I tried using MYSQL_TYPE_ENUM with several buffer types(short, int, long) but so far I only get: Prepared statement error: 2036, state: HY000, Buffer type is not supported The client library version is: 10.4.3 Is there an example how to bind an enum field for both input and output in a prepared statement ?
