Hi,
Can someone help me extract the queue name from the following API functions
void MQENTRY GetBefore ( PMQAXP pExitParms
, PMQAXC pExitContext
, PMQHCONN pHconn
, PMQHOBJ pHobj
, PPMQMD ppMsgDesc
, PPMQGMO ppGetMsgOpts
, PMQLONG pBufferLength
, PPMQVOID ppBuffer
, PPMQLONG ppDataLength
, PMQLONG pCompCode
, PMQLONG pReason
)
void MQENTRY InqBefore ( PMQAXP pExitParms
, PMQAXC pExitContext
, PMQHCONN pHconn
, PMQHOBJ pHobj
, PMQLONG pSelectorCount
, PPMQLONG ppSelectors
, PMQLONG pIntAttrCount
, PPMQLONG ppIntAttrs
, PMQLONG pCharAttrLength
, PPMQCHAR ppCharAttrs
, PMQLONG pCompCode
, PMQLONG pReason
)
void MQENTRY PutBefore ( PMQAXP pExitParms
, PMQAXC pExitContext
, PMQHCONN pHconn
, PMQHOBJ pHobj
, PPMQMD ppMsgDesc
, PPMQPMO ppPutMsgOpts
, PMQLONG pBufferLength
, PPMQVOID ppBuffer
, PMQLONG pCompCode
, PMQLONG pReason
)
I need to log in the queue name and the user id . I was able to get the userid but not able to get the queue name.
Thanks |

Standard MQ programming stuff.
In a normal MQOpen, how do you specify the queue name? Hint: Look in PMQHOBJ.

Thanks Roger, I think I'm missing something here. I do understand that MQHOBJ points to the queue that is opened. I was able to extract the queue name for the OPEN API since I would take it directly from MQOD. Since MQHOBJ is a handle I wasn't sure how to code in C and extract the queue name. I guess I wasn't clear enough. Hope this explains where I'm exactly facing an issue.
Thanks. |

You can only get the queue name during open before and after.
You have to store it as an association to the object handle and then do a lookup when you need it for the other api calls.
I can make this easy for you. I implemented this technique in the mirrorq sample. Download mirrorq1_win.zip from http://www.developer.ibm.com/tech/sampmq.html and look at the mirrorq.c source code. It uses a link list to save the object handles and queue names. You should be able to reuse much of this code.
