The client application can specify interest in getting data along with names belonging to the symbol list while requesting a symbol list. By specifying interest in data along with names, a client application does not need to open individual items belonging to symbol list and the items will be opened and data will be provided. To do this, encode a request message payload with an element list that has an element entry which specifies symbol list behavior.
For Symbol List request messages that specify interest in data, refer to Appendix A.3.1.
For further details, refer to Enterprise Message API C++ Edition Reference Guide.
