Hi all,

I believe I have found a bug in the mmap routine. It manifests itself
when an offset is given that is not zero.

In WindowsNT, when a MapViewOfFile of length `len' is performed at
offset `off', the CreateFileMapping must have at least length
`len'+`off', otherwise the MapViewOfFile function returns an error
(1132, I think).

I have had a look in mmap.cc. The CreateFileMapping function is called
here with length `len'. I believe this should be changed to
`len'+`off'.

Regards,

Ronald Pijnacker
