#includeThis example is similar to Example 1, but it uses a cursor of specific type to perform operations within the transaction. Here, a new cursor is initialized with WT_CURSOR_INIT, and then opened using c->open. The other difference is that the table name is passed as a parameter to establish the table name. Overall, WT_SESSION begin_transaction is a powerful function for managing transactions in WiredTiger.WT_SESSION *session; WT_CONNECTION *conn; WT_CURSORTYPE *cursor; // Open a new session and begin a transaction int ret = wiredtiger_open(NULL, NULL, "create", &conn); if (ret != 0) { // Handle error } ret = conn->open_session(conn, NULL, NULL, &session); if (ret != 0) { // Handle error } ret = session->begin_transaction(session, NULL); if (ret != 0) { // Handle error } // Perform some operations within the transaction using a cursor of specific type WT_CURSOR c; WT_CURSOR_INIT(&c, session, "table:mytable"); ret = c->open(&c, NULL); if (ret != 0) { // Handle error } // ... // Commit the transaction ret = session->commit_transaction(session, NULL); if (ret != 0) { // Handle error } // Close the session and connection session->close(session, NULL); conn->close(conn, NULL);
