For a description of this library see the MariaDB Connector/C page.


  • Added option MYSQL_OPT_CAN_HANDLE_EXPIRED_PASSWORDS for mysql_options()/mysql_optionsv():
    If this option is set, client indicates that it will be able to handle expired passwords by setting the CLIENT_CAN_HANDLE_EXPIRED_PASSWORDS capability flag. If password is expired and CLIENT_CAN_HANDLE_EXPIRED_PASSWORDS is set, the server will not return an error when connecting, but will put the connection in sandbox mode, where all commands will return error 1820/1828 (ER_MUST_CHANGE_PASSWORD/ER_MUST_CHANGE_PASSWORD_LOGIN) unless a new password was set.
