How to use a pre-encoded ElementList in a message Payload?
I have entire ElementList pre-encoded in a buffer. How that buffer should be used to populate the list in a message payload?
RsslBuffer listBuffer; // a buffer with encoded element list in it, 160 bytes RsslElementList list; rsslClearElementList(&list); list.flags = RSSL_ELF_HAS_STANDARD_DATA; list.encEntries = *preencodedListBuf; // when I try to encode the list in a message, the list is always empty rsslEncodeElementListInit(&iter, &list, 0, 0); rsslEncodeElementListComplete(&iter, RSSL_TRUE); // rsslGetEncodedBufferLength(&iter) == 51 – list is not populated
Unfortunately, I was not able to find much info of how to use encEntries neither for ElementList nor for FieldList.
Is this the right way to populate msg payload with pre-encoded ElementList? If not – what is the right one? If yes - what am I possibly doing wrong?

Set the RsslMsg::encDataBody member directly to the buffer that contains your pre-encoded ElementList, e.g.
msg.msgBase.encDataBody.data = "";
msg.msgBase.encDataBody.length = listBuffer.length;
Or, just:
msg.msgBase.encDataBody = listBuffer;
When you call rsslEncodeMsg() the buffer contents will be encoded as the payload.
