 tt_message_barg_add(library call)         tt_message_barg_add(library call)

 NAME    [Toc]    [Back]
      tt_message_barg_add - add an argument to a pattern

 SYNOPSIS    [Toc]    [Back]
      #include <Tt/tt_c.h>
      Tt_status tt_message_barg_add(
      Tt_message m,
      Tt_mode n,
      const char *vtype,
      const unsigned char *value,
      int len);

 DESCRIPTION    [Toc]    [Back]
      The tt_message_barg_add function adds an argument to a pattern that
      may have a byte-array value that contains embedded nulls.

      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 ToolTalk service treats the value as an opaque byte string.  To
      pass structured data, the application and the receiving application
      must encode and decode these opaque byte strings.  The most common
      method to do this is XDR.

      The value argument is the value to be added.  The len argument is the
      length of the value in bytes.

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

      TT_OK     The operation completed successfully.

                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.
