NAME
       tt_message_arg_type - retrieve the type of a message argument

SYNOPSIS
       #include <Tt/tt_c.h>
       char *tt_message_arg_type(Tt_message m,
                                 int n);

DESCRIPTION
       The  tt_message_arg_type()  function retrieves the type of the nth mes-
       sage argument.

       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
       retrieved.  The first argument is numbered zero.

RETURN VALUE
       Upon successful completion, the tt_message_arg_type() function  returns
       the  type  of  the  nth  message  argument.   The  application  can use
       tt_ptr_error(3) to extract one of the following Tt_status  values  from
       the returned pointer:

          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.

APPLICATION USAGE
       The  application  can  use  tt_free(3)  to  free any data stored in the
       address returned by the ToolTalk API.
