NAME
       tt_otype_osig_arg_mode  -  return  the  mode of an argument of a notice
       signature of an otype

SYNOPSIS
       #include <Tt/tt_c.h>
       Tt_mode tt_otype_osig_arg_mode(const char *otype,
                                      int sig,
                                      int arg);

DESCRIPTION
       The tt_otype_osig_arg_mode() function returns the  mode  of  the  argth
       argument of the sigth notice signature of the given otype.

       The  otype argument is the object type involved in this operation.  The
       sig argument is the zero-based index into the notice signatures of  the
       specified  otype.   The  arg  argument is the zero-based index into the
       arguments of the specified signature.

RETURN VALUE
       Upon  successful  completion,  the  tt_otype_osig_arg_mode()   function
       returns  a  value  that  determines  who (sender or handler) 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_OTYPE
                  The  specified  object  type is not the name of an installed
                  object type.
