# mongoc\_client\_session\_advance\_operation\_time(3)

## SYNOPSIS

```
void
mongoc_client_session_advance_operation_time (mongoc_client_session_t *session,
                                              uint32_t timestamp,
                                              uint32_t increment);
```

Advance the session's operation time, expressed as a BSON Timestamp with timestamp and increment components. Has an effect only if the new operation time is greater than the session's current operation time.

Use *mongoc\_client\_session\_advance\_operation\_time()* and *mongoc\_client\_session\_advance\_cluster\_time()* to copy the operationTime and clusterTime from another session, ensuring subsequent operations in this session are causally consistent with the last operation in the other session

## PARAMETERS

- •

  **session**: A *mongoc\_client\_session\_t*.

- •

  **timestamp**: The new operationTime's timestamp component.

- •

  **increment**: The new operationTime's increment component.
