int mysql_options(MYSQL * mysql, enum mysql_option, const void * arg);
mysql- a mysql handle, which was previously allocated by mysql_init() or mysql_real_connect().
mysql_option- the option you want to set. See description below.
arg- the value for the option.
Used to set extra connect options and affect behavior for a connection. This function may be called multiple times to set several options. mysql_options() should be called after mysql_init() and before mysql_real_connect().
Returns zero on success, non zero if an error occurred (invalid option or value).
This function is deprecated as of MariaDB Connector/C 3.0 and will be removed in future releases. It's preferable to use mysql_optionsv.
