lrt_tpcommit

Commits the current transaction.

int lrt_tpcommit( long flags );

The lrt_tpcommit function commits the current System/T transaction.

A transaction in System/T is a logical unit of work that either completely succeeds or has no effect. Transactions allow work being performed by many processes, possibly at different sites, to be treated as a single work unit. The initiator of the transaction can end the transaction using either lrt_tpabort or lrt_tpcommit. lrt_tpcommit can only be called by the initiator of the transaction. If any of the participants cannot commit their portion of the transaction, then lrt_tpcommit fails.

Return Values

If the function ends with an error, it returns -1 and sets the error code in tperrno.

Parameterization

You cannot use standard parameterization for any arguments in this function.

Example

In the following example, the lrt_tpcommit statement commits the transaction if there was no error.

/* Begin a new transaction. Commit if no error*/
tpresult_int = lrt_tpbegin(30, 0);
.
.
lrt_abort_on_error();
lrt_tpcommit(0);
