Message-ID: <1186851804.567302.223160@q4g2000prc.googlegroups.com> (raw)
I'm having trouble with tasking in Ada. I'm used to working with
pthreads
in C/C++... and I'm finding tasks to be somewhat different/annoying.
My basic problem is I want to have 2 threads in my program.
One thread sits in the background and reads in messages,
dispatches them, etc and the other thread reads off a queue
and sends out messages when they are available.
As an analogy, let's assume my background task just got
input from the user (simulating the socket read) and the other
task just printed out stuff.
Something like
procedure main is
begin
task get_name;
task print_something;
task body get_name is
Name : String (1..25);
Last : Integer;
begin
loop
Get_Line (Name, Last);
end loop;
end get_name;
task body print_something is
begin
loop
Put_Line ("blah...");
end loop;
end print_something;
begin --- main
loop;
null;
end loop;
end main;
Of course, this doesn't work as I'd expect. Is there a way to
"timeout" the
first get_name thread... so the OS only waits on that thread for a
short period
of time to allow the other threads to do their business? and then go
back to
the thread?
Thanks
