Hi Pat
If the problem is with the 'Message VAR' not having been initialized, the
TRAP error 2 should have been thrown the first time i use *STRING_RESIZE_VBI
* right? I have analysed further and found that the problem may not be with
STRING_RESIZE_VBI. Am facing the error after the MQ function MQGET has been
called. I face the same error if i am using some other JBASE functions apart
from *STRING_RESIZE_VBI* like *STORE_VBS(Message (STRING *)"")* also.
The following is the part of code in the C function.
MQS_API INT32 MQGet (DP_MPTR INT32 QMgr, INT32 QNum, INT32 MsgMax, INT32
WaitPeriod, VAR * Message)
...
STRING_RESIZE_VBI(Message, MsgMax);
...
MQGET(QManagers[QMgr].QMHeader.HQMcon ,
QManagers[QMgr].Queues[QNum].QHandle ,
&MDescriptor ,
&GetOptions ,
MsgMax ,
Message ,
(PMQLONG)&MsgLen ,
&QManagers[QMgr].Queues[QNum].CompletionCode ,
&QManagers[QMgr].Queues[QNum].ReasonCode
);
SetMQFail(DP_MPRM 0);
*STRING_RESIZE_VBI(Message, MsgLen);*
return MsgLen;
In the above code part '...' signifies coding have been done related to
MQGET, but not of VAR Message.
