The JET_LS data type contains a context handle to local storage (LS).This handle might be associated with a cursor or a table and might refer to dynamically allocated resources.
Windows XP: JET_LS is introduced in Windows XP.
typedef JET_API_PTR JET_LS;
A value of JET_LSNil indicates an invalid context handle.
The context handle can be explicitly disassociated from the JET_LS data type using JetGetLS with JET_bitLSReset. Alternatively, the context handle can be implicitly disassociated from the JET_LS data type when the underlying object is released by the database engine as a result of direct or indirect action by the application. In the implicit case, a runtime callback is issued to the application so that it can clean up the context handle. For more information on implicitly disassociating from the JET_LS data type, see JetSetLS.
The following flags are associated with the JET_LS data type.
The context handle is disassociated from the object.
Set or retrieve the local storage associated with a table cursor.
Set or retrieve the local storage associated with a table.
The context handle is invalid.
Requires Windows Vista or Windows XP.
Requires Windows Server 2008 or Windows Server 2003.
