Generating Transactions Explicitly

To generate a TMF transaction explicitly, follow these steps:

1. Issue an RscBeginTransaction function call to begin the transaction.

2. Issue one or more RscWrite or RscWriteRead calls to alter the content of one or

more rows or records in the database. After each call, examine the return code.

Success (a return value of zero) indicates that the operation completed

successfully and that you can proceed with the next call. Any other return code

indicates that something went wrong and that either the transaction was aborted,

or that you must explicitly abort the transaction by issuing an RscAbortTransaction

function call. Whenever a transaction is aborted, all changes that it made to the

database are backed out.

3. Issue an RscEndTransaction function call (unless you issued the

RscAbortTransaction call which aborts/ends the transaction) to end the transaction.

A return code indicates whether the transaction ended successfully or was

aborted. If the transaction ended successfully, all changes that it made to the

database are committed (made permanent). If the transaction was aborted, any

changes that it made to the database are backed out.
