Problem with MYSQL

[maxorator]

I am using the Mysql C api and the DevPack made for this. But when I am using this code, I always get an Illegal Operation message when running the program:

#include <windows.h>
#include <iostream>
#include <mysql/mysql.h>

using namespace std;

int main()
{
    char *host = "sql1.badblock.com";
    char *user = "theuser";
    char *pass = "thepassword";
    char *db = "thedb";
    MYSQL_RES *result;
    MYSQL *res;

    MYSQL *sock;
    sock = mysql_init(0);
    if (sock) cout << "sock handle ok!" << endl;
    else {
         cout << "sock handle failed!" << endl;
         return EXIT_FAILURE;
    }

    if (res=mysql_real_connect(sock, host, user, pass, db, 0, NULL, 0))
         cout << "connection ok!" << endl;
    else {
         cout << "connection failed!" << endl;
         return EXIT_FAILURE;
    }
    
    mysql_query(res,"SELECT address FROM music WHERE pass=euro8");
    cout<<"Query done!";
    result=mysql_store_result(res);
    cout<<"Store result done!";
MYSQL_FIELD *field;
cout<<"mysql field done!";

while(field = mysql_fetch_field(result))
{
cout<<"in while!";
    cout<<field;
}
cout<<"while done!";
cin.get();
    mysql_close(sock);

    return EXIT_SUCCESS;
}

So I added some couts to see how far the program got, before illegal operation message appears. The last cout displayed is mysql field done. Any ideas?
