Hello,

I'm looking at the implementation of the "restriction" device, from  
Boost.Iostreams library, which provides access to a subsequence of the  
original device.

When it reaches the end of the input subsequence, the restriction device  
start performing read()'s of size zero on the original device.  Shouldn't  
it be returning an end-of-sequence marker (EOF) instead?

I am using a restriction device as source parameter for the  
iostreams::copy function and this always results in an infinite loop.  Am  
I doing something wrong?

Thanks!
