     message's context

SYNOPSIS
     #include <Tt/tt_c.h>

DESCRIPTION
     The tt_message_context_ival() function retrieves the integer
     value of a	message's context.

     The m argument is the opaque handle for the message involved
     in	this operation.	 The slotname argument describes the con-
     text of this message.  The	 value	argument  points  to  the
     location to return	the value.

     If	there  is  no  context	slot  associated  with	slotname,
     tt_message_context_ival()	returns	 a  NULL pointer in slot-
     name.

     function  returns	the status of the operation as one of the
     following Tt_status values:
