TDI

OSR_Community_User · September 27, 2001, 10:49am

Hello,

When opening \device\tcp using ZwCreateFile() it isn’t quite clear to me what the EaBuffer should contain in order to set-up a TCP connection.

Someone has a brief code example of how to initiate a TCP connection using TDI ?

Thanks
Matteo

There is a 1999 article from the OSR “NT Insider” that may help. Fetch TDI.ZIP from this URL:

I’ve the TDI example but that uses UDP and seems to be little different than TCP.

DDK says:

If a local-node client requires connection-oriented communication with a remote-node peer process, the local-node client must first open a transport address and then open a connection endpoint in its underlying transport. The client makes two calls to ZwCreateFile, first to open an address and, then, a connection endpoint.

I can’t understand what should I open with the two calls using the ZwCreateFile API.

First I should open a transport address, then a connection endpoint. One of the call will open (\device\tcp …i suppose…which one ?) and the other ?

someone can help?

Thanks
Matteo

Both must open \Device\Tcp, but the extended attributes are different.

Both Transport Address and Connection Endpoint both opens use \device\tcp.

Address Object Open would have EA buffer pointing to
FILE_FULL_EA_INFORMATION.
EaName field is intialized with TdiTransportAddress. TdiTransportAddress is
#defined in TDI.H to “TransportAddress”.
EaNameLength is initialized to TDI_TRANSPORT_ADDRESS_LENGTH and this is also
#defined in TDI.H
EaValueLength is initialized to sizeof(TA_IP_ADDRESS). Fill in the port and
ipaddress fields in TA_IP_ADDRESS.

Similarly

Connection Object also would have EA buffer pointing to
FILE_FULL_EA_INFORMATION.
with EaNameField initialized to TdiConnectionContext. This is #defined in
TDI.H
with EaNameLength initialized to TDI_CONNECTION_CONTEXT_LENGTH.
with EaValueLength to a sizeof(PVOID) and you could store the address of
connection context in EaValue.

Hope this helps.
-Srin.
