                       Microsoft RPC Version 1.0 Alpha
                                October 1991
                               Hello2 Example

    FILE:       hello2\client.c
    USAGE:      client <servername>
                where  <servername> is the name of the server running the
                server side of the distributed application
    PURPOSE:    Client side of RPC distributed application hello2
    FUNCTIONS:  main() - calls remote procedure HelloProc2
    COMMENTS:
    This version of the distributed application that prints
    "hello, world" on the server features a client that
    manages its connection to the server. It uses the binding
    handle hRpcHello that is defined in the file hello2.h.
