FwpsRedirectHandleCreate0 function (fwpsk.h)

The FwpsRedirectHandleCreate0 function creates a handle that connection redirection functions can use to redirect connections to a local process. For more information about redirection, see Using Bind or Connect Redirection.

Syntax

NTSTATUS FwpsRedirectHandleCreate0(
  const GUID *providerGuid,
  UINT32     flags,
  HANDLE     *redirectHandle
);

Parameters

providerGuid

The provider GUID.

flags

Reserved. Set to zero.

redirectHandle

A pointer to the variable that receives the handle.

Return value

The FwpsRedirectHandleCreate0 function returns one of the following NTSTATUS codes.

Remarks

A callout driver calls the FwpsRedirectHandleCreate0 function to create a handle that can be used to redirect connections.

For more information about redirection, see Using Bind or Connect Redirection.

Your callout driver should call FwpsRedirectHandleCreate0 once and cache the handle so that it can reuse the handle.

Before an Application Layer Enforcement (ALE) connect redirection callout can redirect connections to a local process, it must obtain a redirect handle with the FwpsRedirectHandleCreate0 function and put the handle in the FWPS_CONNECT_REQUEST0 structure. The callout modifies the structure in the classifyFn for the ALE connect redirect layers.

After a callout driver has finished using a redirect handle, it must call the FwpsRedirectHandleDestroy0 function to destroy the handle.
