I have a question, could you please help me?
I want to know how to encode blank data with RSSL_DT_UINT DataType in FieldEntry.
I try to do it like this: fieldEntry.fieldID = 3263; fieldEntry.dataType = RSSL_DT_UINT; rsslEncodeFieldEntry(&encIter, &fieldEntry, NULL);
But I can’t get the expected result.
Could you provide me more details about it? Thanks very much.
Try this, it works for me.
RsslRet AddField( RsslEncodeIterator& encodeIter, RsslInt16 fid, RsslUInt64 value, bool blankData )
{
RsslFieldEntry fe = RSSL_INIT_FIELD_ENTRY;
fe.fieldId = fid;
fe.dataType = RSSL_DT_UINT;
const void* pData = blankData ? NULL : reinterpret_cast<const void*>( &value );
RsslRet rsslReturn = rsslEncodeFieldEntry( &encodeIter, &fe, pData );
if( rsslReturn < RSSL_RET_SUCCESS )
{
boost::format fmt( " AddField Unable to encode UInt64 field %d, %d, Buffer length = %d" );
fmt % fe.fieldId % rsslReturn % rsslGetEncodedBufferLength( &encodeIter );
LogManager::Instance().Log( 2, fmt );
}
return rsslReturn;
}
