The
ksql_trans_commit and
ksql_trans_functions functions commit or
roll-back active database transactions as opened with
ksql_trans_open(3). It is an error to try to
close a transaction that has not been opened. This follows the same underlying
execution logic of
ksql_exec(3). The
id value is used in reporting errors and
making sure that transaction calls are symmetric.
This returns
KSQL_NOTOPEN if the database
connection is not open,
KSQL_TRANS if a
transaction is not yet open,
KSQL_DB if
errors occurred on the database, or
KSQL_OK
on success.
