Hey everyone,
Ive been given this problem and can only make a very scimpy start on it....
can someone please help me??


Synchronise 2 threads: 1 prints 1, second prints 2,
use semiphores for synchronisation (2 needed)
even wait- signal
odd wait- signaal
initial value of semiphores is needed
prints odd one = 1, waits on semiphore,
even= 2, signal odd signals = 3,
guarantee- one thread that prints first, not necessarily the one created first; placement of semiphore is crucial.
if loops are incorrect, one thread may die, if 1 less digit, 2nd loop may be too small. Ensure it still gets the semiphore.

Please Please sort this out....
Thanks
ken

Ps, this has to be written in c/c++

Have you any other informations on how you think you might want this done, or given thought to a layout/plans, even if you dont know how the coding is goning to work have you given thought on what proccesses you want for it to work, cause its much easier to work with (and for me to help with) if its broken down into manageble parts
