The Ultimate Guide to High Availability with MariaDB

Embedded MariaDB Interface

You are viewing an old version of this article. View the current version here.

The embedded MariaDB server, libmysqld has the identical interface as the C client librarylibmysqclient.

The normal usage of the embedded server is to use the normal mysql.h include file in your application and link with libmysqld instead of libmysqlclient.

The intention is that one should be able to move from a server/client version of MariaDB to a single server version of MariaDB by just changing which library you link with.

This means that the embedded C client API only changes when the normal C API changes, usually only between major releases.

The only major change required in your application if you are going to use the embedded server is that you have to call the following functions from your application:

int mysql_library_init(int argc, char **argv, char **groups)
void mysql_library_end(void);

This is also safe to do when using the standard C library.

Notes

  • libmysqld.so has many more exported symbols than the C library to allow one to expose and use more parts of MariaDB. In normal applications one should not use them, as they may change between every release.
  • Before MariaDB 5.5.60 (MariaDB 10.0.35, MariaDB 10.1.33, MariaDB 10.2.15, MariaDB 10.3.7) embedded server library did not support SSL when it was used to connect to remote servers.
