  endpoint ("ncacn_np:[\\pipe\\autorpc]")
]
interface sumup
{
  long SumUp([in] short sumVal);
}

The example file shown here, like all IDL files, contains a uuid (universally unique identifier) value that uniquely identifies this server. The uuid number is generated, along with the stub for the IDL file, by a program named uuidgen. For example, if you type

uuidgen -i

you will get a new IDL stub file containing a new uuid number. The ID number ...
