                      InOut Example

    FILE:       inoutc.c

    USAGE:      inoutc   -n network_address
                         -p protocol_sequence
                         -e endpoint
                         -a server principal name
                         -o options

                         -3 float_value_3

    PURPOSE:    Client side of RPC distributed application inout

    FUNCTIONS:  main() - binds to server and calls remote procedure

    COMMENTS:   This distributed application demonstrates in, out
                parameters.

"This Microsoft RPC Version 2.0 sample program demonstrates\n\
use of the [in], [out], and [in, out] attributes. For more\n\
information about attributes and RPC API functions, see the\n\
Microsoft RPC programming guide and reference.\n\n"

#define DESCRIPTION \
"One [in], one [out], and one [in,out] parameter are defined\n\
for the function InOutProc(). This program displays the values\n\
of these parameters before and after the remote procedure call.\n\n"
