NAME
     tt_message_arg_ival - retrieve the integer value of  a  mes-
     sage argument

SYNOPSIS
     #include <Tt/tt_c.h>
     Tt_status tt_message_arg_ival(Tt_message m,
                                   int n,
                                   int *value);

DESCRIPTION
     The tt_message_arg_ival()  function  retrieves  the  integer
     value 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.   The  value argument is a pointer to an integer where
     the ToolTalk service is to store the contents of  the  argu-
     ment.

RETURN VALUE
     Upon successful completion, the tt_message_arg_ival()  func-
     tion  returns the status of the operation as one of the fol-
     lowing Tt_status values:

        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),  or,  if  the value in the message is not
                yet set (as it would be in observing a request in
                state  TT_SENT  and  trying to look at the TT_OUT
                arguments).

        TT_ERR_POINTER
                The pointer passed does not point to an object of
                the correct type for this operation.
