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.
