IFWXIOCompletion

All overlapped operations require the filter to implement this interface to carry out data pumping.

Notes to Implementers

When calling a method that begins an overlapped operation, the filter must pass to that method a pointer to the IFWXIOCompletion interface. The Firewall service calls the IFWXIOCompletion interface of the filter when the overlapped operation completes.

ISA Samples that Use IFWXIOCompletion Methods

The method IFWXIOCompletion::CompleteAsyncIO is used in the following sample filters provided with ISA:

• ConnectorFilter
• DbgDump
• ExeBlock
• ServerSplit
• SMTPFLTR

Example Code

See Simple Implementation of CompleteAsyncIO in the IFWXDataFilter topic earlier in this section.
