Add all arguments before the message is sent. To change existing argu- ment values, the application must use only modes TT_OUT or TT_INOUT. Adding arguments when replying to a message produces undefined 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 han- dler 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 value argument is the value to be added. RETURN VALUE Upon successful completion, the tt_message_iarg_add() 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.
