int mysql_stmt_store_result(MYSQL_STMT * stmt);
stmt- a statement handle, which was previously allocated by mysql_stmt_init().
You must call mysql_stmt_store_result() for every query that successfully produces a result set (SELECT, SHOW, DESCRIBE, EXPLAIN), and only if you want to buffer the complete result set by the client, so that the subsequent mysql_stmt_fetch() call returns buffered data.
Returns zero on success, nonzero if an error occurred.
You can detect whether the statement produced a result set by checking the return value of mysql_stmt_result_metadata() function.
