Configuration files

By default MariaDB Connector/C doesn't read any configuration file, this needs to be forced either by setting the option MYSQL_READ_DEFAULT_FILE or MYSQL_READ_DEFAULT_GROUP:

/* process options from a configuration file which is not in standard place */
rc= mysql_options(mysql, MYSQL_READ_DEFAULT_FILE, "/home/jeff/config/my_config.cnf");

/* Only process options from group my_app */
rc= mysql_options(mysql, MYSQL_READ_DEFAULT_GROUP, "my_app"`);

Default location of configuration files

If a group (or an empty group) was specified, MariaDB Connector/C looks for configuration files in the following locations:

Windows

1. System windows directory
2. System directory
3. Windows directory
4. C:\
5. MARIADB_HOME environment variable

Posix/Linux

1. SYSCONFDIR (if Connector/C was build with server package)
2. /etc/
3. /etc/mysql
4. MARIADB_HOME environment variable
5. .my.cnf in home directory of the current user

Default groups

In addition to the specified group MariaDB Connector/C will process options from the following groups:

1. [client]
2. [client-server]
3. [client-mariadb]
4. [group] (if specified via mysql_options)
