Re: Does mysql_real_connect allocate memory?

[Anna Fowles-Winkler]

Hi,

I tried taking out the new MYSQL, and my application dumps -- it doesn't look like mysql_init is actually allocating memory for the MYSQL object because then mysql_real_connect is called with a NULL pointer.

Is that supposed to happen?

Hi!
mysql_init will detect if 'mysql' is a NULL pointer or not and allocate
accordingly. However, your code below doesn't initialize 'mysql' that way,
so your results are undefined. I'd recommend:

MYSQL *mysql = NULL;

mysql_init (mysql);
mysql_real_connect(mysql, host, user, password, dbase, 0, 0, 0);

OR

MYSQL mysql;

mysql_init (&mysql);
mysql_real_connect(&mysql, host, user, password, dbase, 0, 0, 0);

Hi,

Does the MySQL C API function mysql_real connect allocate memory or do I
need to do it? This is what my code currently does:

MYSQL *mysql;
mysql = new MYSQL
mysql_init(mysql);
mysql_real_connect(mysql, host, user, password, dbase, 0, 0, 0);

Thanks,
Anna
