int main( void ){
char host[20];
char user[20];
char pass[20];
 
my = mysql_init(NULL);
 
 
sprintf(host,"localhost");
sprintf(user,"username");
sprintf(pass,"password");
 
if (my == NULL ) {
printf("Cant initalisize MySQL\n");
return 1;
}
 
if( mysql_real_connect (my,host,user,pass,NULL,0,NULL,0)  == NULL) {
  printf("Error cant login\n");
  } else {
  printf("Login correct\n");
  }
 
mysql_select_db(my,"test");
mysql_query(my, "INSERT INTO `test`.`collection`"
	        " (`id`, `name`, `title`, `published`)"
		" VALUES (NULL, 'Demian', 'Debian 6.0', '2013-02-14');");
