How can one retrieve the Symbol Limit programatically from the eSignal API? Thanks in advance.

To determine the symbol list limit for a user’s account, you can use the DbcAddDMSymbol() function as illustrated below:
DbcAddDMSymbol(<connection>, "$WRSYMCNT", eADVISE);
Once this request is sent, the application will receive a GeneralLong update whenever the eSignal Data Manager symbol count changes. Use the following fields in the GeneralLong data structure to determine the user’s symbol list limits:
Last contains the Symbol Limit for the user. A value of 0
means the user has no limits.
Prev contains the current symbol count.
Open contains the data base symbol count.
You can also refer to this information in Chapter 5 of the Standard C++ documentation.
