    Description

      When the server parses my.cnf or other option/configuration files, dashes and underscores are interchangeable in options:

      Dashes (-) and underscores (_) in options are interchangeable.

      https://mariadb.com/kb/en/library/configuring-mariadb-with-option-files/#option-file-syntax

      This is not the case with MariaDB Connector/C:

      Unlike with the server, dashes (-) and underscores (_) in options are not interchangeable for MariaDB Connector/C. Options must be specified exactly as they are defined.

      https://mariadb.com/kb/en/library/configuring-mariadb-connectorc-with-option-files/#option-file-syntax

      I think it would be pretty easy to fix this.

      One potential fix would be to modify the _mariadb_set_conf_option function, so that it makes a copy of the config_option C-string argument and replaces all underscores (_) with dashes (-) before doing the strcmp:
