For obvious resons, it is desirable to be able to do output of data to
different devices in parallel. Does the Ada95 standard define what
happens if two tasks try to do IO to two different files at the same
time? I have tried to find out by reading both the RM and the
Rationale, but is none the wiser.
Does one become blocked, waiting for the operation to complete, then
the other becomes blocked, waiting for the operation to complete
(which is what i fear)?
Do both tasks block, then wake up as soon as their respective IO
operations are finished? This is what I would like.
Or, is it simply undefined and left to the implementation?
