- Microsoft RPC Version 2.0
- Copyright Microsoft Corp. 1992, 1993, 1994- 1996
- yield Example
-
- FILE: yields.c
-
- USAGE: yields -p protocol_sequence
- -e endpoint
- -m max calls
- -n min calls
- -f flag for RpcServerListen
-
- PURPOSE: Server side of RPC distributed application yield
-
- 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 yield.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.
