Set - MQ_SET_EXIT

MQ_SET_EXIT provides a set exit function to perform before and after MQSET call processing. Use function identifier MQXF_SET with exit reasons MQXR_BEFORE and MQXR_AFTER to register before and after MQSET call exit functions.

The interface to this function is:

MQ_SET_EXIT (&ExitParms, &ExitContext, &Hconn, &Hobj, &SelectorCount,
             &pSelectors, &IntAttrCount, &pIntAttrs, &CharAttrLength,
             &pCharAttr, &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.

Hobj (MQHOBJ) - input

Object handle.

SelectorCount (MQLONG) - input

Count of selectors

pSelectors (PMQLONG) - input/output

Pointer to array of selector values.

IntAttrCount (MQLONG) - input

Count of integer attributes.

pIntAttrs (PMQLONG) - input/output

Pointer to array of integer attribute values.

CharAttrLength (MQLONG) - input/output

Character attributes array length.

pCharAttrs (PMQCHAR) - input/output

Pointer to character attribute values.

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 */
        MQHOBJ   Hobj;            /* Object handle */
        MQLONG   SelectorCount;   /* Count of selectors */
        PMQLONG  pSelectors;      /* Ptr to array of attribute selectors */
        MQLONG   IntAttrCount;    /* Count of integer attributes */
        PMQLONG  pIntAttrs;       /* Ptr to array of integer attributes */
        MQLONG   CharAttrLength;  /* Length of char attributes array */
        PMQCHAR  pCharAttrs;      /* Ptr to character attributes */
        MQLONG   CompCode;        /* Completion code */
        MQLONG   Reason;          /* Reason code qualifying completion code */

The queue manager then logically calls the exit as follows:

MQ_SET_EXIT (&ExitParms, &ExitContext, &Hconn, &Hobj, &SelectorCount,
             &pSelectors, &IntAttrCount, &pIntAttrs, &CharAttrLength,
             &pCharAttrs, &CompCode, &Reason)

Your exit must match the following C function prototype:

void MQENTRY MQ_SET_EXIT (
PMQAXP    pExitParms,       /* Address of exit parameter structure */
PMQAXC    pExitContext,     /* Address of exit context structure */
PMQHCONN  pHconn,           /* Address of connection handle */
PMQHOBJ   pHobj,            /* Address of object handle */
PMQLONG   pSelectorCount,   /* Address of selector count */
PPMQLONG  ppSelectors,      /* Address of ptr to array of selectors */
PMQLONG   pIntAttrCount;    /* Address of count of integer attributes */
PPMQLONG  ppIntAttrs,       /* Address of ptr to array of integer attributes */
PMQLONG   pCharAttrLength,  /* Address of character attribute length */
PPMQCHAR  ppCharAttrs,      /* Address of ptr to character attributes array */
PMQLONG   pCompCode,        /* Address of completion code */
PMQLONG   pReason);         /* Address of reason code qualifying completion
                               code */
