Register subscription - MQ_SUB_EXIT

MQ_SUB_EXIT provides an exit function to perform before and after subscription reregistration processing. Use function identifier MQXF_SUB with exit reasons MQXR_BEFORE and MQXR_AFTER to register before and after subscription registrationcall exit functions.

The interface to this function is:
MQ_SUB_EXIT (&ExitParms, &ExitContext, &Hconn, &pSubDesc, &pHobj, &pHsub, &CompCode, &Reason)
where the parameters are:

    ExitParms (MQAXP) - input/output
    Exit parameter structure.

    ExitContext (MQAXC) - input/output
    Exit context structure.

    Hconn (MQHCONN) - input/output
    Connection handle.

    pSubDesc - input/output
    Array of attribute selectors.

    pHobj - input/output
    Object handle

    pHsub (MQHOBJ) input/output
    Subscription handle

    CompCode (MQLONG) - input/output
    Completion code, valid values for which are:

      MQCC_OK
      Successful completion.

      MQCC_WARNING
      Partial completion.

      MQCC_FAILED
      Call failed

    Reason (MQLONG) - input/output
    Reason code qualifying the completion code. If the completion code is MQCC_OK, the only valid value is:

      MQRC_NONE
      (0, x'000') No reason to report.

    If the completion code is MQCC_FAILED or MQCC_WARNING, the exit function can set the reason code field to any valid MQRC_* value.


C language invocation

The queue manager logically defines the following variables:
        MQAXP    ExitParms;      /* Exit parameter structure */
        MQAXC    ExitContext;    /* Exit context structure */
        MQHCONN  Hconn;          /* Connection handle */
        PMQSD    pSubDesc;       /* Subscription descriptor */
        PMQHOBJ  pHobj;          /* Object Handle */
        PMQHOBJ  pHsub;          /* Subscription handle */
        MQLONG   CompCode;       /* Completion code */
        MQLONG   Reason;         /* Reason code qualifying completion code */
The queue manager then logically calls the exit as follows:
MQ_SUB_EXIT (&ExitParms, &ExitContext, &Hconn, &pSubDesc, &pHobj, &pHsub,
             &CompCode, &Reason);
Your exit must match the following C function prototype:
        PMQAXP    pExitParms;      /* Exit parameter structure */
        PMQAXC    pExitContext;    /* Exit context structure */
        PMQHCONN  pHconn;          /* Connection handle */
        PPMQSD    ppSubDesc;       /* Subscription descriptor */
        PPMQHOBJ  ppHobj;          /* Object Handle */
        PPMQHOBJ  ppHsub;          /* Subscription handle */
        PMQLONG   pCompCode;       /* Completion code */
        PMQLONG   pReason;         /* Reason code qualifying completion code */
