Download Release Notes Changelog About MariaDB Connector/C

Release date: 20 July 2017

This is a Stable (GA) release of the MariaDB Connector/C, formerly known as MariaDB Client Library for C.

For a description of this library see the MariaDB Connector/C page.

Features

  • Array support for prepared statements (bulk operations)
  • TLS/SSL support for GnuTLS, Windows SChannel and LibreSSL
  • Support for passphrase protected keys
  • SHA256 authentication plugin

New API functions

  • mariadb_get_info and mariadb_get_infov (variable argument list): for obtaining general and connection specific values.
  • mariadb_get_charset_by_name and mariadb_get_charset_by_nr: returns character set information for a given internal number or name of character set. These functions have been previously used internally by MariaDB Connector/ODBC and are now exported, so they can be used also within plugins.
  • mysql_reconnect which was used internally before (if the option MYSQL_OPT_RECONNECT was set) is now part of the API and can be used by applications and plugins to reestablish a failing connection
  • mariadb_cancel: aborts a connection immediately by making all subsequent read/write operations fail
  • mariadb_stmt_execute_direct: prepares and executes a prepared statement for one time execution
  • mysql_stmt_warning_count returns: the number of warnings from the last executed statement
  • mysql_reset_connection: resets the current connection and clears session state
  • Functions for obtaining session state changes:
    • mysql_session_track_get_first()
    • mysql_session_track_get_next()
