Options with the Embedded Server
Any options that may be given with the mysqld server daemon, may be used with an embedded server library. Server options may be given in an array as an argument to the mysql_library_init(), which initializes the server. They also may be given in an option file like my.cnf. To specify an option file for a C program, use the --defaults-file option as one of the elements of the second argument of the mysql-library-init() function. See , "mysql_library_init()", for more information on the mysql_library_init() function.
Using option files can make it easier to switch between a client/server application and one where MariaDB is embedded. Put common options under the [server] group. These are read by both MariaDB versions. Client/server-specific options should go under the [mysqld] section. Put options specific to the embedded MariaDB server library in the [embedded] section. Options specific to applications go under section labeled [ApplicationName_SERVER]. See , "Using Option Files".
