This function finalizes the MySQL library, which should be
done when you are done using the library. However,
mysql_library_end() should be
used instead. See Section 22.214.171.124, “mysql_library_end()”.
To avoid memory leaks after the application is done using
the library (for example, after closing the connection to
the server), be sure to call
explicitly. This enables memory managment to be performed to
clean up and free resources used by the library.
