NS_NewPipe is an internal API.  You can instantiate it via the
component manager via the @mozilla.org/pipe;1 contract ID.  Use
nsIPipe to configure the object.

Also, you might want to consider using nsIWebBrowserStream instead of
nsIDocShell::LoadStream.  nsIDocShell is an internal interface that is
not really intended to be used outside the internals of Mozilla.

Hi,
I am expanding the embedding examples for windows and trying to pass
data streams directly to the docShell with
docShell->LoadStream which takes as an input an nsIInputStream.

I can write to a nsIOutputStream and that is fine.

but if I want to use NS_NewPipe (in, out... I will have to change the
linking because i get an unresolved external error:

do I necessarily have to link against xpcom_core.lib?

because then it works, but the GRE is not enough anymore and some dlls
are needed (xpcom_core, nspr4, plc4, plcds4) in the path, just for 1
line of code.

Is there a way to circumvent this?

Thanks
