In C++ it probably must be declared as extern "C" unsigned ...
That's not runtime adjustment. The stack is allocated in the strtup code, and
uses the value in _stklen. Is you change it afterwards (say as first line in
main()) that will have no effect.
No side effect other than they both are ignored. :)

I just ran into a problem. Is there something in WIN32 like the ctirical
section in DOS was?   CCriticalSection can be used tiside one proces to keep
threads separate. Global mutexes I can use to sincronice between processes ot
applications, if they are all aware.
But isn't there a simpler method to prevent a task switch for a short section
in the program?  I have a program that is polling directories and moves the
files that apper there to another directories. Another program creates those
files. In several places it simply uses MoveFileEx itself. I found it works
in practice. Bus thinking a bit deeper I consider it's not really safe that
way. What if a task switch occours when the system is in the middle of
MoveFileEx? The poller might start to transfer an incomplete file. (Well,
that probably doesn't happen as I look for file length and it should be >0 to
start a job, and that is probably updated last. But think of the problem in
more general way.)
Well, OTOH if a task could allocate the execution the same way we were back
to old windoze where anyone can lock up the whole system. So probably that
thing really doesn't exist on the user level.

JERRY COFFIN was observed on 31-Aug-97, writing to ROGER SCUDDER
          Something about: void main() again / size
 Ah... Jerry...
 I want to take it in the direction of C++ so I moved it to
 the C++ echo.
 Speaking only of decelerations for now... I want to get away from
 decelerations of main and discuss function decelerations other
 that main.   A function deceleration and a function prototype
 are the same thing, right?  I mean a prototype does not
 allocate memory.  I'm not sure just how it works, but you can
 not call a function until it had been defined, right?  So is
 a prototype just a string literal that the compiler can use
 as a guide to check against any subsequent definitions of the
 function for differences?  Is the prototype copied into some
 reference table or something?
 Going back to the original thread, The book I am reading right
 now, which may be outdated (1994) on this topic, states that an
 ANSI C compiler will evaluate a prototype (or deceleration)
 int foo() and int foo(...) as equivalent. OTOH, a C++ compiler
 will interpret int foo() as meaning int foo(void).  It states
 that the syntax int foo() is obsolete under C++.
 Thanks. I didn't make a strong connection to that point when I
 read it.  Now that you reinforced it I have it down and clear.
 Right, but I want to explore decelerations of other functions.
 I want to know if you agree with the book (FWIW - it is named
 "The Revolutionary Guide to OOP Using C++") that int foo() is
 obsolete under C++ and that a C++ compiler will not evaluate
 a deceleration of int foo() as equivalent to int foo(...) as
 is the behavior for a ANSI C compiler.
 phewwwww.... a lot of words to cover a simple detail... It's all
 based around the topic of porting C programs to C++.

assistant: You may want to hide both str and n and provide operator char* and operator

What happens if you already have a Roman string created?  You lose memory...
try deallocating the string, first.  Better yet, use the string class rather
than the char* with strdup.
I'm not convinced it works, but your test program tests my suspicions, so
I'll just have to try it.  :->
Yeah, I was worried about that.  First of all, you have a str[1000] that's
never used in the .cpp portion.  :-)
Second, a few other test cases:
IL = 49  [core dumped!]
IIC = 98
VC = 95
And, the slightly more obscure:
IVC = 96
These are a few that you fail on.  Your algorithm, I'm guessing, would have
to be completely reworked to accomodate these.  Especially if you want to not
allow, say:
IVCV ?? 101
This is why the Roman Numeral problem is difficult.  Not impossible - you
still follow a straight-forward methodology to come up with the "conversion"
- but it's got a lot of little quirks.  :-)
Good luck!

 they have implemented special macros known as "message crackers"
 that replace most of the long switch statement code.  It's still

assistant: Neil Heller, All, 23 Aug 97, 08:59
 Your mistake here is assuming that the different code fragments for
different cases in `switch' behave like seperate blocks. In reality, all
fragments belong to the same code, and `switch' can be thought of as a
`goto' statement with the different `case' statements acting as labels.
 So, in reality, the code you wrote looks something like:
 {
    if (foo == 1)
      goto L1;
    if (foo == 2)
      goto L2;
    goto L3;
  L1:
    int bar = 1;
    goto L3;
  L2:
    int bar = 2;
  L3:
 }
 I hope you realize that this code is illegal, because it tries to define
the variable `bar' twice within the same block. Therefore, your compiler
errors weren't for the declaration of `bar', but for its RE-declaration
within the same block.
 Hope this helps,

 Somebody already answered your question, but I also wish to note that your
code is broken, because it removes the string's terminating zero.
Apparently, you happened to have a zero right after the last byte of
string[], but you obviously cannot count on it. Also, you only allocated 6
chars for the string, while the full "12345\n" string requires 7 chars (5
numerals, one newline, one zero).
 The correct code should look like:
   char string[7];
   strcpy(string, "12345");
   string[strlen(string) + 1] = 0;
   string[strlen(string)] = '\n';
 Notice that I add the new terminating zero BEFORE changing the old one, so
that the subsequent call to strlen() would be defined.
 Of course, even better code would be:
    char string[7];
    strcpy (string, "12345");
    strcat (string, "\n");
 Hope this helps,

Write your reply.

assistant: No.  There  are  some  cases where switch statements make sense. There
aren't any cases where gotos make sense.
But switch statements tend to grow larger and larger  (more  and  more
cases) as the system evolves. Before adding a switch statement, it's a
good idea to think about solving the problem  using  dynamic  binding.
This  will  make  the initial code more expensive to write, but future
extensions will be cheaper.
