I have a question about the use of the ANSI C (not C++) Standard Library
in kernel code for w2k/xp/vista.
I've been told, somewhat in passing, by a good kernel developer, that
the standard library functions (strcpy, qsort, etc) cannot be used in
kernel code because "you can end up coming out of them in the wrong
state". (We were talking about something else at that moment and he was
avoiding getting into the full explanation).
So, I'm not quite sure what he meant by that - I wonder now if he was
talking about calling conventions? in the DDK, all the...The use of the C++ standard
[I'm not positive if this should go here or comp.std.c++, so I hope
you'll forgive me if you feel it is off topic here.]
I've programmed in C++ for several years now (think 5 years seriously,
and maybe 8 from when I made my hello world), and I'm debating whether
or not I should buy the C++ standard document. So I have a couple
questions about it.
1. Under what circumstances would you recommend buying it? Is it useful
for mostly just compiler/library implementers, or do you guys use it in
everyday programming? If so, how?

I'm interested in asynchronous programming but am having a few problems
understanding the underlying implementation.
I assume that asynchronous programming is generally done by calling a
function (which includes a call back function pointer in its arguments)
which starts a thread and then immediately returns. Once the thread has
completed the task it then calls the call back function to return the
data to the caller.
Is this the basic idea of asynchronous programming or have I got it
Thankfully threading is now on-topic in this group thanks to C11.
...Standard Library of useful utilities in C...
I'm new to c programming, and I come to it from higher-level, object
oriented languages. I was hoping to find a standard library that
contained common structures and functions that would be used in many C
programs. As an example, I am looking for a standard implementation of
a hash table.
Does such a library exist? I checked out the GNU C Library, but it
didn't seem to have what I was looking for.
Does every C programmer implement this stuff from scratch?

Recently the discussion about the integer flags started again.
I argued again with my "_carry()" function, but
Mr Jean Marc Bourguet and Mr K. Thompson proposed
a better alternative. Thinking about it, I think that their
solution is much better than mine, since it produces less
restrictions and fits better in the existing language.
We could do something like:
int add_with_carry(int a,int b, bool *carry);
int sub_with_borrow(int a,int b,bool *borrow);
int mult_with_carry(int a,int b,bool *carry);
The advantage of this is that in machines that do not have any carry

I am using Visual C to run a program that uses IDL functions to process
data. But now I want to have C open IDL GUIs at specific times. The
problem that I am having is that all the calling of IDL from C that I
have done so far has been with functions. And all the GUI work is done
with procedures. Does anyone know of a way to call an IDL GUI from
Visual C and then return the GUI variables to C?
Sorry, this response may be a bit weak but no one else has stepped up...
Why don't you write your GUI procedures as functions? A simple wrapper
would suffice. Maybe I am missing something.

Using the Forte 11 (Sun C++ 5.8) compiler on a Solaris 10 system, most
of the source files are C++; however there are a few standard c source
files mixed in; I want to compile these using standard c rules, not C+
+, so the compiler doesn't complain about C++ keywords. Is there a
compile option that will force a standard c, rather than a C++,
compile? Something similar to the GNU GCC compile option "-x c".

I guess you could have a look at rename() method declared in stdio.h.
It might be there in the non-deprecated <cstdio>.

A sanity check: is the C++ Standard Library (STL) used much in the
game industry? In all my years of C++, I've avoided learning or using
it. Before bothering to write a bunch of code with it, I'd like to
know if it's a common industry practice, or if it is common to avoid
it in favor of homebrew. I do know that it was only within recent
years that MSVC got its act together with a fully working, standard
STL. So maybe I'm not quite the dinosaur I think I am? When I first
learned C++ in 1993 the STL was not worth bothering with.

I was wondering if anyone would know if the standard C++ library

I understand that the library is provided by "Rogue Wave", who in turn
seem to base their source on the "Apache C++" library. I have tried

Hello good people in c.l.f.!
I've used interop features of C/Fortran before, but this endeavor is a
little different in that this goes in the other direction from what I
have previously written, where C calls my unbelievably-effective fortran
functions. (That might be the other/other direction for others; we all
have our perspectives, usually carved by experience.)
So I would like to call a C function that will return this data, and
fortran does not know the size of the thing being passed to it. I
believe this can be achieved by allocatables, but here's the C of it:
