    For any given compiler, sizeof(unsigned) is a constant, so in line 72 the
conditional expression is a constant. Is this what you intended? It seems the
wrong way round to me.

    It's easy to sort that out. Just do:-
    void invert(float *f)
    {   *f = 1/(*f);
    }
    Just checked on the calculator. It does make sense to take the reciprocal
of a float (e.g. 1/pi). Another 'arrowing experience. :-)

assistant: Hi Tom,
    OK on both comments. However, everybody seems to have missed the point.
    Having read all his posts, I have to conclude that all John Dumas really
wants is to make turnkey disks.
    Making a turnkey disk is a trivial JCL task, and not a C problem at all.
Each operating system provides detailed instructions in its manuals for going
about it. The three primarily concerned are OS/2, Windows in its various
incarnations and MS-Dos, although others like Unix, Xenix, Linux, PICK and
Multi-User Dos are also implemented on the PC.
    If John wishes to go to netmail, most of us can provide him with the
necessary instructions (I can for all but PICK). I just think it's probably a
bit off-topic here.

Yes. It's my way of being a bit more economical with memory on 16-bit
systems, while not unnecessarily restricting myself on 32-or-more-bit
stems.
Why? On 32-bit systems I allocate memory for 16000 line pointers at a time,
on 16-bit systems only 1000. The other way round would seem quite illogical
to me.
However, there are 2 instances of stricmp() still in the program that I
forgot to replace with strcmp(). Noone has pointed this out so far :-)

assistant: Hello everyone!
I'm a 14 year old (15 years 19 March) programmer and wounder how I can use
the memory above 640Kb....
Right now I trie to programm (I'm not a very good programmer...) a little
game, where you see everything from above (like Red Alert, but not that
good)... And I need alot memory for images, viritual screens, sounds, maps
and so on...
 The problem is that i use farcalloc() to allocate memory, and this function
doesn't give me enoung memory.... I think it is EMS or XMS memory I should
use... but how do I allocate XMS or EMS (or whatever it should be) memory to
my program, and how do I read/write from/to it?
I have a Borland C++ 3.1 compiler (DOS).

assistant: NOTE: DCTEdit v0.04 [7]
Ok I think this thread should stop pretty soon, two reasons: 1. It's off
topic, and 2. I have already solved the problem by populating the main code
with calls to the routine that was previously the timer ISR, and timed too.
The reason for waiting in the ISR and not skipping until the next one was
because the next one occured 55ms later which was too much of a delay to be
acceptable.
Thanks to everyone who has helped with this, took me a while to see that
there really was a more reliable(albeit not so nice) way of doing it.

G'day John,
This is an age old debate..:)
It can be done on certain compilers, when used with a certain OS.
I have written code which returned the size of any allocated buffer owned or
not, without failure in DOS and BC2.0. Same code failed bismally under WIN,
and with two other compilers in DOS as well.
Some said that just before the address of the memory block, 4-8 bytes hold
the info to the size of the data.I suppose that may work when going through
assembly and allocating memory straight from DOS, but in C we're under the
compiler's or its RTL's preferred allocation scheme..
Play it safe. Ask for the buffer-size, then allocate + 1.
Better way is to ask for an already allocated buffer, that way all you have
to do is a NULL check to verify. That is a safer way of doing things anyway
and if something screws up, it's the caller's fault.
If in need, have another function in your DLL to specify the data size reqd.
Eg, caller could go :
char *buf = malloc(Johns_Func_Needs() * sizeof(char));
 if(NULL != buf) Johns_Func(buf);

2. Searching a database for an answer, constructing a reply.
3. Writing an answer addressed to the right person.
And the robots Bod (Mine) and InfoMail (Damian Walker)
More complex, and you have less control. It is a valid option
though, but it all depends what the target system is.
Before we can suggest any ideas - we need to know more - specifically,
what message bases you'll be working on. JAM, Squish, Hudson, Opus etc.
Opus is by far the easiest to parse, but has significant drawbacks

 I'm not an expert on PC architecture, but as I understand it,
 free and malloc are calling the operating system.  It's the
 OS who is doing all the work.  free and malloc are interface
 functions that are used to get and pass addresses.
 Yes but how does it know the address?  It takes a pointer to a
 block previously allocated with malloc.   This is why it is
 important to keep track of such pointers. Memory leaks happen
 when someone forgets to call free before assigning that pointer
 to another block.
 I am not certain, but I think the starting addresses and lengths
 are stored in a table by the operating system.  The C functions
 ask the operating system for a block of a certain size.  The OS
 returns either an address (which we assign to a pointer) or else
 communicates with (possibly by setting a register flag) that it
 can not produce the requested block.
 When we make a request to free the memory the OS takes the address
 and looks it up in the table where the size is recorded and makes
 that memory available again.  Sort of like when they take one of
 those reserved signs off a table in a restaurant.
 Right, '\0' is only useful in string handling and really has
 nothing to do with dynamic memory allocation.
 I hope I have been of some help and not just hashed over stuff
 you already understand.
