Is there any documentation that states the intention behind these files: try.hpp,option.hpp,result.hpp,some.hpp,none.hpp? Because I found use of some of those files quite similar. If any one please point me some documentation on these library files or reply me with their purposes on mail, I would be very pleased. -- Regards, --------------------------------------------------------------------------------------- Abhishek Dasgupta Linux Software Developer - Linux Technology Centre IBM Systems Lab, IBM India Pvt.
