Subscription request - MQ_SUBRQ_EXIT

MQ_SUBRQ_EXIT provides a subscription request exit function to perform before and after subscription request processing. Use function identifier MQXF_SUBRQ with exit reasons MQXR_BEFORE and MQXR_AFTER to register before and after subscription request call exit functions.

The interface to this function is:

MQ_SUBRQ_EXIT (&ExitParms, &ExitContext, &Hconn, &pHsub, &Action, &pSubRqOpts,
               &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.

pHsub (MQHOBJ) input/output

Subscription handle

Action (MQLONG) input/output

Action

pSubRqOpts (MQSRO) input/output

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 */
        PMQLONG  pHsub;          /* Subscription handle */
        MQLONG   Action;         /* Action */
        PMQSRO   pSubRqOpts;     /* Subscription Request Options */
        MQLONG   CompCode;       /* Completion code */
        MQLONG   Reason;         /* Reason code qualifying completion code */

The queue manager then logically calls the exit as follows:

MQ_SUBRQ_EXIT (&ExitParms, &ExitContext, &Hconn, &pHsub, &Action, &pSubRqOpts,
               &CompCode, &Reason);

Your exit must match the following C function prototype:

void MQENTRY MQ_SUBRQ_EXIT (
PMQAXP    pExitParms,       /* Address of exit parameter structure */
PMQAXC    pExitContext,     /* Address of exit context structure */
PMQHCONN  pHconn,           /* Address of connection handle */
PPMQHOBJ  ppHsub;           /* Address of Subscription handle */
PMQLONG   pAction;          /* Address of Action */
PPMQSRO   ppSubRqOpts;      /* Address of Subscription Request Options */
PMQLONG   pCompCode,        /* Address of completion code */
PMQLONG   pReason);         /* Address of reason code qualifying completion
                               code */
