 NAME    [Toc]    [Back]
      tt_message_arg_xval_set - serialize and set data into an existing
      message argument

 SYNOPSIS    [Toc]    [Back]
      #include <Tt/tt_c.h>
      Tt_status tt_message_arg_xval_set(

      xdrproc_t xdr_proc,
      void *value);

 DESCRIPTION    [Toc]    [Back]
      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.
