FILE: repasu.c

PURPOSE: Utility functions used by both client and server
sides of the RPC distributed application.
This sample demonstrates the transmit_as example.
A doubly-linked list is transmitted over the network
as a sized array.

RELATED: repass.c - server main
repasp.c - remote procedures
repasc.c - client main

FUNCTIONS: CHAR_STRING_to_local - convert CHAR_STRING to WCHAR_STRING
CHAR_STRING_from_local - convert WCHAR_STRING to CHAR_STRING
CHAR_STRING_free_inst - free WCHAR_STRING memory
CHAR_STRING_free_local - free CHAR_STRING memory
midl_user_allocate - user-supplied memory allocator
midl_user_free - user-supplied routine to free memory


COMMENTS: This sample program generates a client and server can share
an interface, but one side can use a different representation
than the other.

The client side in this example does all operations using
character strings, and the server side does all operations
using UNICODE strings. Two procedures are provided, one
defined with ASCII strings, one with UNICODE strings.
The wire format reflects these definitions, yet the client
and server see pure ASCII and pure UNICODE respectively.

The [represent_as] attribute (used in the client and server
side acf files) requires the four user-supplied functions
whose names start with the name of the transmitted type
(in the client side's case: WCHAR_STRING)

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.
