I have this problem I want to try to over come, consider..
task type t1 is
entry a;
entry done;
end t1;
task type t2 is
entry a(** access to type t1 **);
entry b;
end t2;
task body t1 is
T: t2;
begin
loop
select
accept a(**pointer to me**);
T.b;
...
or
accept done;
...
end select;
end loop;
end t1;
task body t2 is
C: **task t1 pointer**
begin
loop
select
accept a(**task pointer**) do
C := task pointer;
end;
...
*task pointer*.done;
or
...
end t2;
How would I go about passing the task pointer ? I read in DejaNews where
someone put up a similar question about equivalent to C++'s *this
pointer, and their response suggested to use the type name as the this
pointer.
I tried this and got a gnat bug message when I tried to use the
Unchecked_Access' command!
Does anyone have a workaround ?
Thanks, Paul
