14: PURPOSE: Server side of RPC distributed application xmit
15: FUNCTIONS: main() - registers server as RPC server
16:
17: COMMENTS: This sample program generates a linked list to
18: demonstrate how the list can be transmitted over
19: the network more efficiently as a sized array.
20: The pointers are rebuilt on the server side.
21:
22: The [transmit_as] attribute (used in the typedef of
1.1.1.2 ! root 23: DOUBLE_LINK_TYPE in the file XMIT.IDL) requires the
1.1 root 24: four user-supplied functions whose names start with
1.1.1.2 ! root 25: the name of the presented type, DOUBLE_LINK_TYPE.
1.1 root 26:
27: The [in, out] attributes applied to remote procedure
28: parameters require the two user-supplied functions
29: MIDL_user_allocate and MIDL_user_free.
30:
31: The other functions are utilities that are used to
32: build or display the data structures.
