TdiBuildAssociateAddress macro

TdiBuildAssociateAddress sets up an internal device control IRP for a TDI_ASSOCIATE_ADDRESS request to the underlying transport in which a local-node client has already opened an address and a connection endpoint.

Syntax

VOID TdiBuildAssociateAddress(
  [in] PIRP           Irp,
  [in] PDEVICE_OBJECT DevObj,
  [in] PFILE_OBJECT   FileObj,
  [in] PVOID          CompRoutine,
  [in] PVOID          Contxt,
  [in] HANDLE         AddrHandle
);

Parameters

  • Irp [in]
    Pointer to a client-supplied IRP, either originating in a higher level network component or allocated with TdiBuildInternalDeviceControlIrp.

  • DevObj [in]
    Pointer to the device object created by the underlying TDI transport driver.

  • FileObj [in]
    Pointer to a file object representing the connection endpoint.

  • CompRoutine [in]
    Specifies the entry point of a client-supplied IoCompletion routine or NULL. The I/O manager calls this routine when the given IRP is completed, unless the client sets this parameter to NULL.

  • Contxt [in]
    Pointer to a client-determined context. This client-supplied pointer is passed in to the IoCompletion routine when it is called with the completed IRP. Contxt is NULL if CompRoutine is NULL.

  • AddrHandle [in]
    Specifies a handle to a file object representing a local-node address.

Return value

None

Remarks

TdiBuildAssociateAddress sets IRP_MJ_INTERNAL_DEVICE_CONTROL as the MajorFunction and TDI_ASSOCIATE_ADDRESS as the MinorFunction codes in the transport's I/O stack location of the given IRP.

A kernel-mode client must open both a connection endpoint and an address with successful calls to ZwCreateFile before it calls TdiBuildAssociateAddress. The client must make the associate-address request before it makes a connection to the remote node either with a request set up with TdiBuildListen, optionally followed by one set up with TdiBuildAccept, to the transport driver or with a request set up with TdiBuildConnect to the transport driver.

However, a client can get and/or set information about the open connection or address with one or more requests set up with TdiBuildQueryInformation and/or TdiBuildSetInformation before making the associate-address request.

After the client associates the connection endpoint with the address, it can make any other TDI_XXX requests to the transport on the just-associated connection with one exception: it cannot make a TDI_ASSOCIATE_ADDRESS request again for the specific endpoint until it makes a successful TDI_DISASSOCIATE_ADDRESS request to the transport.

Note   The TDI feature is deprecated and will be removed in future versions of Microsoft Windows. Depending on how you use TDI, use either the Winsock Kernel (WSK) or Windows Filtering Platform (WFP). For more information about WFP and WSK, see Windows Filtering Platform and Winsock Kernel. For a Windows Core Networking blog entry about WSK and TDI, see Introduction to Winsock Kernel (WSK).
