- Microsoft RPC Version 2.0

- repas Example
- 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: WCHAR_STRING_to_local - convert WCHAR_STRING to CHAR_STRING
- WCHAR_STRING_from_local - convert CHAR_STRING to WCHAR_STRING
- WCHAR_STRING_free_inst - free CHAR_STRING memory
- WCHAR_STRING_free_local - free WCHAR_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.
