The Close Procedure
These steps explain the sequence of procedure calls given in Table 4-12.
1. To close a file, call FTM_CLOSE_REQ_.
a. If the procedure succeeds, it returns a status code of ZAPS-VAL-STATUS-OK.
If the procedure fails, it returns a different status code. To obtain the details of
an error at this stage, call APS_STATUS_, specifying as input the CEPI
returned by the FTM_INITIALIZE_REQ_ procedure for this association.
b. If the association is in nowait mode, call MFM_AWAITIOX_ to wait for
completion of the FTM_CLOSE_REQ_ call. MFM_AWAITIOX_ gives you the
status code for the completed procedure call. For more information on the
MFM_AWAITIOX_ procedure, refer to the OSI/FTAM Programming Reference
Manual.
c. If you call MFM_AWAITIOX_ and the status code returned is not
ZAPS-VAL-STATUS-OK, call APS_STATUS_, specifying as input the CEPI
returned by the FTM_INITIALIZE_REQ_ procedure for this association.
2. Next, to receive a close confirm event, call APS_EVENT_RECEIVE_. In wait
mode, this procedure returns a status code of ZAPS-VAL-STATUS-EVENT when
you receive an event. If APS_EVENT_RECEIVE_ returns a different status code,
to obtain the details of an error at this stage, call APS_STATUS_, specifying as
input the CEPI returned by the FTM_INITIALIZE_REQ_ procedure for this
association.
a. If the association is in nowait mode, call MFM_AWAITIOX_ to wait for
completion of the APS_EVENT_RECEIVE_ call and to obtain the status code.
A status code of ZAPS-VAL-STATUS-EVENT means you received an event.
Table 4-12. Calls for Closing an FTAM File Using FTM_CLOSE_REQ_
Step Action to Take Procedure(s) to Call
1 Close the previously opened file. FTM_CLOSE_REQ_
a. If error returned by FTM_CLOSE_REQ_, check
status.
APS_STATUS_
b. If nowait mode, await completion of
FTM_CLOSE_REQ_.
MFM_AWAITIOX_
c. If error returned by MFM_AWAITIOX_, check status. APS_STATUS_
2 Get the next event. APS_EVENT_RECEIVE_
a. If nowait mode, await completion of
APS_EVENT_RECEIVE_.
MFM_AWAITIOX_
3 Check status: Is the event a close confirm? Or, if
APS_EVENT_RECEIVE_ returns a status other than
ZAPS-VAL-STATUS-EVENT, is there an error?
APS_STATUS_
4 Retrieve service confirm information. FTM_CLOSE_CNF_
