Re: compressed exports/imports on NT ?

Hi,

Not sure, whether this are real unix-like pipes, but on NT you can address file streams.

echo hi > myfile:pipe # create a stream called 'pipe' + write to it more < myfile:pipe # would read it.

explorer shows a file called myfile with 0 bytes.

never tried it for anything useful though. Please post a message, if these streams behave like one would expect from named pipes.
