strange error with mysql_stmt_init()

The code looks like this.

MYSQL *conn;
MYSQL_STMT *stmt;

..... /* some code set the conn */

stmt = mysql_stmt_init(conn);
if(stmt == NULL)
printf("%d\n", mysql_errno(conn));


When I run this, i got that: stmt is NULL, and the printed errno is 0.
I checked that the error code of mysql_stmt_init() is 2008 when it's out of memory.

So it seems the conn is ok and no error, but the mysql_stmt_init returns NULL.

I'm realy sorry for asking this question , finally i found the reason. It's my bad of write the wrong code, not something wrong with the mysql_stmt_init(). The reason is so stupid and make me feel stupid. I'm sorry for what i have done.

We have all been there at least once. Relax, get another cup of coffee,
and, enjoy the day.
