# mongoc\_client\_session\_commit\_transaction(3)

## SYNOPSIS

```
bool
mongoc_client_session_commit_transaction (mongoc_client_session_t *session,
                                          bson_t *reply,
                                          bson_error_t *error);
```

Commit a multi-document transaction.

## PARAMETERS

- •

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

- •

  **reply**: A maybe-**NULL** pointer to *overwritable storage* for a *bson\_t* to contain the results.

- •

  **error**: An optional location for a *bson\_error\_t* or **NULL**.

## RETURN

Returns true if the transaction was committed. Returns **false** and sets **error** if there are invalid arguments, such as a session with no transaction in progress, or if there is a server or network error.

If a **reply** is supplied, it is always initialized and must be freed with *bson\_destroy()*.
