I want to use some functionality of a mono class in python (I have very
little experience in python). The examples I've found of using c# in python
all start with:

Because they're different implementations of the same API, and they have
different optimizations and so on.
Mono is 90+% .NET compatible, but be aware that and so on also means that
certain low level implementations may exist on one platform but not on
another or have subtle differences.

SqlDecimal uses the Math.Pow, which fails apparently due to Bug #7938 ( hard

there may be a patch. I'll check that out.

Yes, I figured out that it probably boiled down to Math.Pow - there are a
couple of other bugs that also seem to be downstream side effects of this.

I'm finding that if I run height8's example code exactly as is, as an
independent application, it works as expected.
If I use that identical code to watch a UnixSignal and to shut down my
application, there is no indication that SIGTERM, SIGINT or SIGQUIT are
being caught. The big difference is
I'm new to signals. Looking over the Mono docs, and various articles on the
web, it's clear that this has evolved as Mono matured. I just want to make
sure I understand how it actually works today, and what I should expect.
I see in this documentation:
It may be that I'm partly overthinking this. I see that the console has a

least, it, ahem, *should be* trivial.

Yes, this could well be it. I have a couple of unmanaged libraries that are

I have some questions about Mono.Unix.Pipes.
I have been using this with some success, but I am relatively new to Linux,
and the mono documentation that I have found is missing or incomplete. The
Linux manual pages docs on pipes are clearly referring to a different animal
than this.
Sorry, I'm not understanding your response. Are you suggesting I somehow read
a byte array directly rather than sending it back via a pipe (which I'm
doing now)?
I'm looking into unix domain sockets as an alternative, but I struggling to
find documentation and examples for that also.

I have long had a working C# app that consumes data piped from the C library

child processes.

use of Mono.Unix.UnixPipes - the documentation for
Ubuntu 12.04, Mono
I thought I had installed complete mono, but MonoDevelop only shows
Mono.Audio, .CSharp, and 6 other namespaces through Mono.Xml, but not
Mono.Unix.
What have I missed ?
