MySQL 5.7 C API Developer Guide

Abstract

This is the MySQL 5.7 C API Developer Guide. This document accompanies MySQL 5.7 Reference Manual.

The C API provides low-level access to the MySQL client/server protocol and enables C programs to access database contents. The C API code is distributed with MySQL and implemented in the libmysqlclient library.

For legal information, see the Legal Notices.

For help with using MySQL, please visit the MySQL Forums, where you can discuss your issues with other MySQL users.
