What is [sys].[sp_columns_100_rowset] used for?

[HoustonGuy]

It appears [sys].[sp_columns_100_rowset] simply returns schema data for a DB, or table. I see it being called in a trace I have on a DB, but I'm not sure why a process would use this system SP.
It's being called via RPC by VS2013 application. (Either manually, or automated - I can't tell.)

Any thoughts?

Thanks in advance.

It's typically used by applications that employ server-side cursors to process the data.
