**CLIENT  *open_ace_server (char *host , u_long prog, u_long vers );
**
**
** Client creation routine for a program "prog" and a version "vers".
** "host" identifies the name of the host where the server is.
** If successful it returns a client handle, otherwise it returns NULL.
** NOTES : "prog" and "vers" are defined in "nace.x" and for this 
**         version "prog" can be only "NET_ACE" and "vers" can be only 
**         "NET_ACE_VERS".
**         The transport protocol currently supported is only TCP 
**         ( not UDP).
*******************************************************************
*******************************************************************
**
**void close_ace_server (CLIENT *cl );
**
**
** This routine destroys the client's RPC handle, which was created
** by "open_ace_server"
*******************************************************************
*******************************************************************
**
**int call_ace_server (CLIENT *cl, net_data *data_for_srv,
**		       net_data **data_for_cln, int timeout );
**
**
** Call the remote procedure "ace_server_1" ( name of this procedure 
** is "hard coded" in this version ) associated with the client handle 
** "cl", which is created by "open_ace_server". "data_for_srv" are the
** data, which are to be sent to the server, "data_for_clnt"  is  the result.
** "timeout" is the time allowed for a response from the server.

**
**
** This routine waits for RPC requests to arrive, and calls the call back 
** procedure "call_back" with "data_in" and "data_out".
** Normaly, this routine returns only in the case of same errors.
