/****************************************************************************
Microsoft RPC Version 2.0
Copyright Microsoft Corp. 1992, 1993, 1994- 1996
xmit Example
FILE: xmits.c
USAGE: xmits -p protocol_sequence
-e endpoint
-m max calls
-n min calls
-f flag for RpcServerListen
PURPOSE: Server side of RPC distributed application xmit
FUNCTIONS: main() - registers server as RPC server
COMMENTS: This sample program generates a linked list to
demonstrate how the list can be transmitted over
the network more efficiently as a sized array.
The pointers are rebuilt on the server side.
The [transmit_as] attribute (used in the typedef of
DOUBLE_LINK_TYPE in the file XMIT.IDL) requires the
four user-supplied functions whose names start with
the name of the presented type, DOUBLE_LINK_TYPE.
The [in, out] attributes applied to remote procedure
parameters require the two user-supplied functions
midl_user_allocate and midl_user_free.
The other functions are utilities that are used to
build or display the data structures.
