Asyncronous call to task

Asyncronous call to task

[Lisa Ansellotti]

how can i call a entry in a task without block my main thread?

i need to do something like this:

in the main:

task1.start;

in the task:

task body task1 is
	begin	
        accept start;
        --return the control to the main thread but continue the task1 jobs

or 

in the main

task1.start (with a parameter that runs the task1.start asyncronously)



thank you

I was in the middle of my reply when I got interrupted, which is why
it arrived after this message.

FWIW - would my reply have been of any use?

Once the accept statement completes the rendezvous is complete so the
main and task1 will continue independently. The only synchronous bit
is the rendezvous here; when the main calls the task1.start entry it
will wait until task1 is ready at the "accept start;" line.

If you were to do something like:

   accept start do
      blah...
   end start;

then called it from main, main would wait until the "end start" before
going on its merry way.

Hope this helps. If not, I've misunderstood your question.
