NAME
       tt_message_arg_xval_set  - serialize and set data into an existing mes-
       sage argument

SYNOPSIS
       #include <Tt/tt_c.h>
       Tt_status tt_message_arg_xval_set(Tt_message m,
                                         int n,
                                         xdrproc_t xdr_proc,
                                         void *value);

DESCRIPTION
       The tt_message_arg_xval_set() function serializes and sets data into an
       existing message argument.

       The  m  argument  is the opaque handle for the message involved in this
       operation.  The n argument is the number of the argument to be changed.
       The  first  argument  is  numbered  zero.  The xdr_proc argument causes
       tt_message_arg_xval_set() to serialize the data pointed to by value and
       store  it  as  a  byte string value of the nth argument of the message.
       The value argument is the data to be serialized.

RETURN VALUE
       Upon  successful  completion,  the  tt_message_arg_xval_set()  function
       returns  the  status of the operation as one of the following 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 cor-
                  rect type for this operation.

          TT_ERR_NUM
                  The integer value passed was invalid (out of range).

          TT_ERR_XDR
                  The XDR procedure failed on the given data, or evaluated  to
                  a zero-length expression.
