ncacn_spx

endpoint( ncacn_spx:link-address[port-name] )

link-address

Specifies the host server. This may be either a character string (the server name), or a 20 digit hexadecimal number that consists of the host server s network address (8 digits)concatenated with the node address (12 digits). See Remarks for instructions on how to obtain the network address and node address. A null string specifies the local computer.

port-name

Specifies an optional 16-bit number that represents the socket address. Values can range from 1 to 65,535. When no value is specified, the endpoint-mapping service selects a valid port-name value.

Example

[ uuid(12345678-4000-2006-0000-20000000001a),

version(1.1),

endpoint("ncacn_spx:[1000]")

] interface foo

Remarks

The ncacn_spx keyword identifies SPX as the protocol family for the endpoint.

The syntax of the SPX transport port string, like all port strings, is defined independently of the IDL specification. The compiler performs some syntax checking but does not guarantee that the endpoint specification is correct. Some errors may be reported at run time rather than during compilation.

When using the ncacn_spx transport, the server name is exactly the same as the 32-bit Windows NT name. However, since the names are distributed using Novell protocols, they must conform to the Novell naming conventions. If a server name is not a valid Novell name, servers will not be able to create endpoints with the ncacn_spx transport. The following is a partial list of characters prohibited in Novell server names:

* + . / : ; < = > ? [ ] \ |

The ncacn_spx transport is not supported by the version of NWLink supplied with MS Client 3.0.

16-bit Windows client applications that use the ncacn_spx transport require that the file NWIPXSPX.DLL be installed in order to run under the Windows NT Windows on Windows (WOW) subsystem. Contact Novell to obtain this file.

Note To obtain the network and node addresses, use Novell s comcheck utility, or the Novell-defined API IPXGetInternetAddress. On Windows NT, you can also obtain these addresses with the ipxroute configTo obtain the network and node addresses, use Novell s comcheck utility, or the Novell-defined API IPXGetInternetAddress. On Windows NT, you can also obtain these addresses with the ipxroute config command.
