Open - MQ_OPEN_EXIT

MQ_OPEN_EXIT provides an open exit function to perform before and after MQOPEN call processing. Use function identifier MQXF_OPEN with exit reasons MQXR_BEFORE and MQXR_AFTER to register before and after MQOPEN call exit functions.

The interface to this function is
MQ_OPEN_EXIT (&ExitParms, &ExitContext, &Hconn, &pObjDesc, &Options,
&pHobj, &CompCode, &Reason)
where the parameters are:

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

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

    Hconn (MQHCONN) - input
    Connection handle.

    pObjDesc (PMQOD) - input/output
    Pointer to object descriptor.

    Options (MQLONG) - input/output
    Open options.

    pHobj (PMQHOBJ) - input
    Pointer to object 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 */
        PMQOD           pObjDesc;       /* Ptr to object descriptor */
        MQLONG          Options;        /* Open options */
        PMQHOBJ         pHobj;          /* Ptr to object handle */
        MQLONG          CompCode;       /* Completion code */
        MQLONG          Reason;         /* Reason code */
The queue manager then logically calls the exit as follows:
MQ_OPEN_EXIT (&ExitParms, &ExitContext, &Hconn, &pObjDesc, &Options,
              &pHobj, &CompCode, &Reason);
Your exit must match the following C function prototype:
void MQENTRY MQ_OPEN_EXIT (
PMQAXP          pExitParms,     /* Address of exit parameter structure */
PMQAXC          pExitContext,   /* Address of exit context structure */
PMQHCONN        pHconn,         /* Address of connection handle */
PPMQOD          ppObjDesc,      /* Address of ptr to object descriptor */
PMQLONG         pOptions,       /* Address of open options */
PPMQHOBJ        ppHobj,         /* Address of ptr to object handle */
PMQLONG         pCompCode,      /* Address of completion code */
PMQLONG         pReason);       /* Address of reason code qualifying
                                   completion code */
