0021 DESCRIPTION
0022 -----------
0023 Change the logic of how *tx_commit(3)* or *tx_rollback(3)* shall behave.
0024
0025 Setting affects current transaction and is used during the phase when commit
0026 or abort is performed. The setting value is stored in thread local stored for
0027 particular control thread.
0028
0029 Parameter 'control' accepts following values:
0030
0031 - *TX_UNCHAINED* this is *default* value. Meaning that when commit or rollback has
0032 been performed, the current control thread will not be in transaction, i.e.
0033 thread have left any global transaction.
0034
0035 - *TX_CHAINED* means that when transaction is committed or rolled back, a new
0036 transaction is started. The start of new transaction is performed only those
0037 cases when there is proper context for it. For example is commit or abort
0038 encouraged protocol error, the new transaction is not started. The commit/rollback
0039 error and new transaction state is returned combined error code. If error is
0040 received during starting next transaction, the error code is corrected (summed)
0041 with *TX_NO_BEGIN* error code.
0042
0043
0044 RETURN VALUE
0045 ------------
0046 On success, *tx_set_transaction_control()* return *TX_OK*; on error, error code is returned
0047
0048 ERRORS
0049 ------
0050
0051 *TX_EINVAL* The value of 'when_return' is not *TX_UNCHAINED* nor
0052 *TX_CHAINED*.
0053
0054 *TX_PROTOCOL_ERROR* Transaction manager is not open by *tx_open(3)*
