    NAME
         tt_message_xarg_add  -  add  an  argument   with   an   XDR-
         interpreted value to a message object
    
    SYNOPSIS
         #include <Tt/tt_c.h>
         Tt_status tt_message_xarg_add(Tt_message m,
                                       Tt_mode n,
                                       const char *vtype,
                                       xdrproc_t xdr_proc,
                                       void *value);
    
    DESCRIPTION
         The tt_message_xarg_add() function adds an argument with  an
         XDR-interpreted value to a message object.
    
         To change existing argument values, the application must use
         only modes TT_OUT or TT_INOUT.
    
         Adding arguments when replying to a message  produces  unde-
         fined results.
    
         The m argument is the opaque handle for the message involved
         in  this  operation.   The n argument specifies who (sender,
         handler, observers) writes and  reads  a  message  argument.
         The following modes are defined:
    
            TT_IN   The argument is written by the sender and read by
                    the handler and any observers.
    
            TT_OUT
                    The argument is written by the handler  and  read
                    by the sender and any reply observers.
    
            TT_INOUT
                    The argument is written by  the  sender  and  the
                    handler and read by all.
    
         The vtype argument describes the type of argument data being
         added.  The xdr_proc argument points to the XDR procedure to
         be used to serialize the data  pointed  to  by  value.   The
         value argument is the data to be serialized.
    
    RETURN VALUE
         Upon successful completion, the tt_message_xarg_add()  func-
         tion  returns the status of the operation as one of the fol-
         lowing Tt_status values:
    
            TT_OK   The operation completed successfully.
    
            TT_ERR_MODE
                    The specified Tt_mode is invalid.
    
            TT_ERR_NOMP
                    The ttsession(1) process is not running  and  the
                    ToolTalk service cannot restart it.
    
            TT_ERR_POINTER
                    The pointer passed does not point to an object of
                    the correct type for this operation.
    
            TT_ERR_XDR
                    The XDR procedure failed on the  given  data,  or
                    evaluated to a zero-length expression.
