How to pass streamId in a batch message.

manning0218

Is there a way to pass a specific streamId when encoding a message.

In the example we have this:

for(i = 0; i < itemCount_; i++)
		{
			itemName.data = marketPriceItemInfoList_[i].itemname;
			itemName.length = marketPriceItemInfoList_[i].nameLength;
			marketPriceItemInfoList_[i].streamId = ++streamId;
			if((ret = rsslEncodeArrayEntry(&encodeIter, &itemName, 0)) < RSSL_RET_SUCCESS)
			{
				printf("rsslEncodeArrayEntry() failed with return code: %d\n", ret);
				return ret;
			}
		}

which is the for loop when sending a batch request. What I was wondering if there is a way when dealing with encoding a batch request to send a specific streamId in rsslEncodeArrayEntry()?

If not how is the streamId determined when the request is finished being processed?

Hi @manning0218,

The streamID in a batch request is set when setting up the request message.

RsslRequestMsg msg = RSSL_INIT_REQUEST_MSG;
...

/* set-up message */
msg.msgBase.msgClass = RSSL_MC_REQUEST;
msg.msgBase.streamId = streamId;

However, the streamId associated with the batch request is only used to acknowledge the receipt of the request. When the Provider successfully receives the request, the application will receive a status message indicating the batch was received and will close the stream. It is up to the application, through REFRESH and STATUS messages to determine when the complete batch has been processed.
