IO in async task or overlapped IO ?

Question

hi,  

   what's different between OVERLAPPED IO and sync IO in async task ?  I think the io in an async task is easier  than overlapped io, that need not deal with OVERLAPPED struct.

But is any performance degradation in much async task IO ?

thanks!

Hi Frank,

Can you please explain in more detail what you are trying to do? Are you asking this in the context of a Metro style app?
