Close cursor or deallocate cursor

When the cursor command is TDS_CURSOR_CLOSE, the client is requesting to close a cursor. This can be a request to both close and deallocate the cursor, or to close it only.

When the cursor command is TDS_CURSOR_DEALLOC, the client is requesting to deallocate a cursor.

In response to either command, the Gateway-Library transaction calls the following functions:

Function	Action
TDCURPRO	Determine: The type of cursor command, and Whether the cursor should also be deallocated.
[application logic]	[Close the cursor]
TDCURPRO	Send the cursor status to the client.
TDSNDDON	Send the reply to the client.
TDGETREQ	Retrieve the next part of the cursor request.
