requests and responses and is only compiled in when --enable-developer
is passed to configure. It includes server and client side code for
generating and responding to functions on this pipe. The functions are:
- AddOne: add one to the uint32 argument and return ig
- EchoData: echo back a variable sized char array to the caller
- SourceData: request a variable sized char array
- SinkData: send a variable sized char array and throw it away
There's a win32 implementation of the client and server in the
junkcode CVS repository in the rpcecho-win32 subdirectory.
