Prerequisites
Your application can issue a Reset operation at any time after the transactional interface or Requester is loaded, as long as the client issuing the Reset call has established a connection with the transactional interface—for example, by opening a file or by requesting the status of a file using a Pervasive PSQL utility.
Procedure
1
Set the Operation Code to 28.
2
Set the Key Number and Key Buffer to 0.
Result
If the Reset operation is successful, the transactional interface performs the following actions for the specified client, window, or session:
1
Aborts any active transactions.
2
Releases all locks held.
3
Closes all open files.
If the Reset operation is unsuccessful, the transactional interface returns a nonzero status code.
Positioning
The Reset operation destroys all currencies because it closes any open files.
