MySql version: 5.1.62

In mysql-5.1.62\mysql-5.1.62\sql-common\client.c, at line 1889

mysql->methods = &client_methods;

It set MYSQL* methods funtion pointer address to static MYSQL_METHODS client_methods array.

My question is why not initialized it in mysql_init just like OOP`s construct.

Actually it is initialized (to 0) in mysql_init.
Why do you prefer 'an earlier' link to the static struct?

Thank CPanllini, it might be MYSQL mysql static struct object, then mysql_init(&mysql), it is bad 'an earlier' link to static mysql struct object;

But in my situation, MYSQL* mysql = mysql_init(NULL); it my_malloc mysql pointer object, it is suitable to set the funtion pointer address.
