 tt_message_xarg_add(library call)         tt_message_xarg_add(library call)

 NAME    [Toc]    [Back]
      tt_message_xarg_add - add an argument with an XDR-interpreted value to
      a message object

 SYNOPSIS    [Toc]    [Back]
      #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    [Toc]    [Back]
      The tt_message_xarg_add function adds an argument with an XDRinterpreted
 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 undefined

      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    [Toc]    [Back]
      Upon successful completion, the tt_message_xarg_add function returns
      the status of the operation as one of the following Tt_status values:

      TT_OK     The operation completed successfully.

                The specified Tt_mode is invalid.

                The ttsession(1) process is not running and the ToolTalk
                service cannot restart it.

                The pointer passed does not point to an object of the
                correct type for this operation.

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