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 returned. The first argument is numbered zero. RETURN VALUE Upon successful completion, the tt_message_arg_mode() function returns a value that 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 application can use tt_int_error(3) to extract one of the following Tt_status values from the Tt_mode integer return value: TT_OK The operation completed successfully. TT_ERR_NOMP The ttsession(1) process is not running and the ToolTalk service cannot restart it. TT_ERR_NUM The integer value passed was invalid (out of range). TT_ERR_POINTER The pointer passed does not point to an object of the cor- rect type for this operation.
