 NAME    [Toc]    [Back]
      tt_message_arg_type - retrieve the type of a message argument

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

 DESCRIPTION    [Toc]    [Back]
      The tt_message_arg_type function retrieves the type of the nth message
      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    [Toc]    [Back]
      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
                correct type for this operation.

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