Commit phase 2 of a two-phase transaction.

The |
This function finalizes a transaction, discarding the rollback buffer and invalidating the transaction handle. Any object handles scoped to the transaction become invalid. However, calling
mco_trans_commit_phase2()when the transaction is in an error state will cause a rollback.
| MCO_S_OK | The transaction was committed successfully |
|
MCO_S_NOTFOUND |
Index not found when trying to remove object’s entries from index |
| MCO_E_NOMEM | Out of memory, possibly during an attempt to create an index |
|
MCO_S_DUPLICATE |
Duplicate value in a unique index (or duplicate OID) |
|
MCO_E_TRANSACT |
The transaction was in an error state |

rc = mco_db_open_dev( dbname, simple_get_dictionary(), &dev, 1, &db_params );
if ( MCO_S_OK != rc )
{
rc = mco_db_connect( dbname, &db );
...
rc = mco_trans_start(db, MCO_READ_ONLY, MCO_TRANS_FOREGROUND, &t);
