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 */
