Re: [Dev-C++] Coreleft() alternative

[Per W. <pw...@ia...>]

It isn't so easy to return amount of memory left in a Windows environment,
since the memory architecture looks so much differnt.

Howerver, i assume that the old program was running under DOS, i.e.
limited to 640kB memory. Because of the great increase of available memory
together with swap space, most programs don't need to bother keeping track
of amount of free space.

If you really want to look into it, there are a number of Win32 API calls
to check on the memory subsystem, but is your program regularly
expected to consume 50-500 MB or more?

The two main things to care about are:
- not leaking memory, maging the app requiring regular restarts.
- handling a failed memory allocation (NULL pointer or exception depending
on how application is configured to behave).

Just for fun, the app might keep track of amount of memory it has
allocated, to warn users that operation xx might require huge amounts of
memory (for example undo of a global search/replace in a megalarge
spreadsheet, text document, ...)

[Dev-C++] Coreleft() alternative

Hi,

I'm porting some c source code for a DOS program written with Borland. =

Re: RES: [Dev-C++] Does anybody have experience with GPL?

[Per W. <pw...@ia...>]

If you post just a binary, you have to be prepared to handle requests for
the source for a reasonable copying fee and within a reasonable time
frame. In short, if you publish the binary, you should publish the source
too at the same time.

The goal of the GPL is about the freedom of the receiver, i.e. that they
should have the freedom to fix bugs themselves, or add missing features
etc. Obviously, that requires access to the source.

Why do you want to keep the source for 6 months? Do you need time to clean
up the code, or are there other issues at hand?

By the way - it is normally best to include the list in the exchanges, to
avoid redundant answers or comments.

If that's what the IEEE said then that's what we'll use while

Re: [Dev-C++] Out of memory in function main()

[Alfred P. R. <al...@ya...>]

My suggestion would be to break it up into modules, individual C++ files.  Maybe in the range of 1000-2000 each, or whatever works for you.  If you've already done that, then maybe compile individually then link together.
   
  I've found a few references to Fatal F1008 on the Web, none related to Dev-C++:
  Windows NT, Borland C++ 5.4, 1999
  Windows 95-XP, Borland C++ 5.0, 2005 Problem using += operator.
  Borland C++ 5.5.1, 2002 Problem caused by 30K+ lines of code, suggests modularizing code.

"Alfred P. Reaud" <al...@ya...> wrote:  That's all in the calculus, and the concept of limits.
   
  In  reality, think about what the zero operation means with respect to  physics and quantum mechanics.  As long as you deal with limits,  the conventional wisdom applies.  But at 0, things reach a  boundary condition.   This is illustrated by the Dirac Delta Function
   
  First,  for edification, let's address the identity: 1/(infinity) = 0, on a  common object, an orange.  This orange, when divided, will  eventually reach a slice which can't be further divided and still give  you an orange slice.  That last slice, though of a molecular  thickness, is still the last slice.  If you divide it further,  you're not dealing with an orange anymore, rather you are dealing with  constituent atoms and molecules.  So you don't get an infinite  number of orange slices, rather you get a finite though large number of  slices.
   
  So  what happens when you actually divide by 0?  Physically, IMHO, you  do not preform the operation.  The physical operation 0 is a null  operation (as in addition and subtraction).  The logic is that if  you try to divide an orange 0 times, you actually don't divide the  orange by anything, i.e. 1/0 = 1 (with respect to physical  objects).  However, the identity 1*0 = 0 still works because as  you're not preforming the multiplication (0 is the null operator,  hence no operation), therefore the sum of additions which make a  multiplication isn't done, so the result is 0.
   
  This must be the reason why general relativity and quantum mechanics don't meet...;^)

x/0 approaches infinity if x gets closer and closer to zero from the

It approaches -infinity if x gets closer and closer to zero from the

Since limes x/0 -> infinity or -infinity depending on direction of

In mathematics (esp. Calculus) you consider a sequence of numbers x
getting closer to zero but without ever reaching it. You can do this by
coming from the negative side (all values of x are negative) or from the
positive side (all values of x are positive). This depends on the point
of interest. That is why they (the mathematicians) often write "x -> +0"
or "x -> -0". The "->" is the mathematical symbol describing the process
"getting closer to ... but without ever reaching ...".

In the case of the function 1/x it is interesting to differentiate
between positive and negative values of x, resulting in different
limits, resp. "1/x -> -infinity for x -> -0" and "1/x -> +infinity for x
-> +0". The simple conclusion is there will be no value for x=0, 1/0 is
undefined.

Re: [Dev-C++] How connect c++ to a database?

[Per W. <pw...@ia...>]

Was that a correction of something that I said?

The limit function (also known as limes, lim) when x reaches zero from the
negative side is -infinity, not infinity, and as I noted, it is
problematic to use limes to define the value of 1/0, since we don't like
the duality of 1/0 being both -infinity and +infinity. Hence it should
normally be treated as "undefined", at least when working with real-valued
numbers. Looking at 1/0 as +infinity is a simplification that should be
avoided.

1/x

Re: [Dev-C++] How connect c++ to a database?

[Per W. <pw...@ia...>]

And that is why I observed that limes 1/x reaches different values when x
reaches zero from positive and negative side, i.e. we either have to
conclude that +infinity is identical to -infinity, or we have to think of
1/0 as just "undefined". In short, thinking of 1/0 as infinity is a
simplification of the problem - my original point.

When talking about division by zero in software-development terms, the
IEEE 754 floating point standard defines:
+n/0 -> +infinity
-n/0 -> -infinity
0/0 -> not a number (NaN)
