Using low-level C libraries in other environments?

[Cut]

My apologies if this post is in the wrong forum.

I'd like to use an SDK written in low-level C and asm. I'm not sure
how this SDK is implemented; I'd have to buy it. So this question is
theoretical.

Is it possible to use a high-level IDE used for another language, such
as Java or C#, to use a C/ASM API?

Thanks for your time,
Cut

'Tis, but I'll try to give enough information for you to decide where
the right place to ask is.

If it's written in C and assembly, it most likely exports entry points
callable from C programs; if you can verify that, you don't have to
care how it's actually implemented - you can just act as if it were
implemented in C.

Probably, but the C language doesn't specify how (which is what makes
comp.lang.c the wrong place to ask).
Since C has fairly simple calling conventions and nearly universal
support, many (most?) higher-level languages make it possible to call into
a library that is, or acts like it is, implemented in C. Some languages
provide this as part of the language; for languages that don't, many
(most?) implementations of the language provide it as an extension.

Look for "native code interface" or "foreign function interface" in your
documentation, and if that doesn't tell you what you need to know try
a newsgroup that discusses the language you're using and/or the tools
you're using.

We'll soon have you at the point where your method only works if the

C itself has no calling conventions. Most C *implementations* define
fairly simple calling conventions. And yes, it's common for other
languages to be able to call C functions, or functions in whatever
language that conform to the local C calling convention. How to use
such a feature is a question for a newsgroup that deals with the other
language, or with a particular implementation of it.

We must do something. This is something. Therefore, we must do this.

Hmmmyes. Something like "C imposes fairly simple constraints on an
implementation's calling conventions" would probably have been closer
to what I meant.

But then, I've been away for a while, and I don't have nearly enough
other ways of keeping in shape for the pedantic nitpickery^W^Wfanatical
devotion to accuracy that's expected around here.

Personally, I think a few of you have too much time on your hands.

Obviously. usenet is filled with such people.

It is not only possible, it is a reality.

But the C Standard has nothing whatsoever to say about how other
languages such as Java or C#--let alone high-level IDE's--interface
with C. Consequently, your question is not really about C, but rather
about another language like Java that can "interface" with C. As such,
you would be better served asking your question in another, more
appropriate newsgroup.
