You already have the code in

if(mysql_stmt_execute(stmt) != 0) {
        printf("Unable to create new session: Could not execute statement\n");
        return NULL;
}

If that fails, you didn't insert any rows. The docs contain a full example

You can also use mysql_stmt_affected_rows() after a successful mysql_stmt_execute() to find out how many rows were insterted/updated/deleted.
