7.1 Function summary

Function parameters accept different events and information from the Extract or Replicat program, pass the information to the appropriate routine for processing and return a response and information to the caller.

Routine	Description
EXIT_CALL_RESULT	Set by the user exit routines and tells the caller how to respond when each exit call completes.
EXIT_CALL_TYPE	Indicates the processing point of the caller and determines the type of processing to perform.
EXIT_PARAMS	Supplies information about the associated `EXIT_REC_BUF` when the call type is `PROCESS_RECORD` or `DISCARD_RECORD`. The exit routines can alter certain `EXIT_PARAMS` to change how the caller processes returned records.
EXIT_REC_BUF	Contains the record about to be processed by Extract or Replicat. `EXIT_REC_BUF` is supplied when the call type is `PROCESS_RECORD` or `DISCARD_RECORD`. Exit routines can change the contents of this buffer, for example, to perform custom mapping functions. When changing the contents of `EXIT_REC_BUF`, change the `SOURCE_FILE` (for Extract processing only) and `RECORD_LEN` parameters appropriately so that external processes can identify the record.
