Hi Ion,

Thank you for getting back.

You can define extra method which does not guaranty to fill rest of file
with zeros. On POSIX it will be filled with zeros. On windows it will/or not
will be filled with zeros. Who cares. Both will conform method
specification. User will be able to choose required behaviour.

For instance my program does not require file to be filled with zeros.
Instead it requires API to be as quick as hardware allows.

Looking forward to hearing from you.

Thanks.

Dima
