 I'm not sure what you are thinking about his question.  I am

 About void pointers and losing type information; this is one
 area where I think C++ has a feature that is lacking in C.
 Function templates, can be a big help when you meed to code a
 function that must handle many different types.  I know that
 is only generates functions for each type.  Still they can
 make the programmers job much easier.
 I know this may be bating an off topic thread, but I am pretty
 sure that it was decided that we could mention C++ as it
 relates to a problem in C.   Now I just hope this doesn't fly

Yes I know.  I am still learning assembly, but I've known that one just
from playing with interrupts. No argument is needed. I am just stating
something I found out while trying to write programs with visual C++ and
GNU.  Borland is the only compiler that I have seen which will use
getch() in the way everyone expects it to work. WIth any other compiler,
it will cut the last NON-cprintf() line. Really suck.
Here is what I have which isn't GNU:
MicroSoft Visual C++ v4.0 & v5.0
Borland C++ v4.00,
Borland C++ for OS/2 v2.0.
GNU Compilers:
Linux (Can't remember)
OS/2 v0.9c w/ upgrade
DOS 272.1 & 280
Windows 95 Not sure (Don't use much)
Windows NT Not sure (Don't use much)
I don't have the Watcom compiler..  That's about it unless you know of
other compilers that I didn't mention.

    Not at all. It comes almost straight out of the standard. :-) That's why
I don't recommend it as bedtime reading for beginners. :-)
    User documentation would look more like this:-
    "If your compiler runs through an operating system, the user function int
main(...) becomes the mandatory starting point. Thus int main(void) or int
main(int argc, char *argv[]) is the gateway from the outside environment to
your C program. It is where you pick up command line arguments for your
program if the operating system provides argc and argv. It is also the
ordinary way to return to the operating system."
    Thank you. Can we all start thinking of int main(...) as above from now
on?
    Neither you nor I have resposnibility for the ambiguity. It is inherent
in any function name that says one thing and does another. :-) What *is* up
to us, I think, is to dispel the myths and help the newbies, BICBW.

Write your reply.

assistant: Hi Richard,
    There are two ways. You can define the player structure to consist of its
own and all the other structures in one huge lump, or you can declare it to
consist of a small structure which contains only pointers to the other
structures.
    The first method gives a single unwieldy structure. The second requires
indirection which can be tricky on disk files. Maybe a tree structure would
be helpful. K&R gives a couple of examples, but there have been whole
libraries written about binary trees, and it's a big subject.
    It's your program, so it's your choice. :-) I don't want to intrude or
impose my ideas which may not be suitable.

user: You are replying to Jasen Betts about "Re: -getch()".

Write your reply.

assistant: What I was trying to say is:
   GetStream(1) which is defined in conio.h filters through and decodes
ANSI ESCAPE charactors.   With the use of cprintf( you can define a
window(1,17,80,25) and cprintf will print in that window and the window
will scrowl automaticly.
     Or if you want to put a menu bar on the bottom of your screen like your
comm terminal, cprint will keep the print in that window after you
define a window(1,1,80,23);
     problem arose when using cprint because when escape charactors came in
progamming a comm terminal.  cprint does not decode those but
other output functions do!   cprint is absent of that feature.  I wanted to
alter my cprint function somehow so that it will have that feature or call
Borland and get another cprint function.
     Borlands BBS number does not answer anymore.

Thanks Bob. I would also point out that this does not apply in the UK as no
method of copyright registration exists, nor do our courts award punitive
damages. I think the Berne convention covers international copyright law and
that is all that should concern us when dealing with copyright of C source
code posted in an international echo such as this.

assistant: Hi Juha-Matti,
No you should use their counter-functions such as fclose().
Also on exiting a program, most compilers will close all files and free all
memory used by the application automatically.

Write your reply.

assistant: Hi Richard,
Somebody else will expalin to you about unions, except to say you don't use
them here. The way I would solve this problem is to have a series of
structures for each facet of the inventory. Then incorporate them in an
overall structure e.g.:
typedef struct _armor{
    /* armor stuff */ } ARMOR;
typedef struct _weapons{
    /* weapons stuff */} WEAPONS;
etc.
typedef struct _inventory{
    ARMOR   *armor;
    WEAPONS *weapons;
    /* other stuff */ } INVENTORY;
INVENTORY is then incorporated into your player structure as:
typedef struct _player{
    INVENTORY   *inventory;
    /* other stuff */ } PLAYER;
And then a series of defines to declare the maximum number of elements for
each facet:
#define MAX_ARMOUR  10
#define MAX_WEAPON  10
etc.
You will then need a small initialization routine (no error checking):
int     InventoryInit( PLAYER *player)
{
    INVENTORY   *Temp;
    Temp = calloc( 1, sizeof( INVENTORY) );
    Temp->armor = calloc( MAX_ARMOUR, sizeof( ARMOR) );
    Temp->weapons = calloc( MAX_WEAPON, sizeof( WEAPONS) );
    player->inventory = Temp;
    return( OKAY);
}
You can access the elements of each facet of inventory with:
    player->inventory->armor->armor_stuff;
    player->inventory->weapons->weapons_stuff;
    etc.
If your inventory list is going to be quite small you may be better not using
dynamic allocation and using normal arrays instead:
typedef struct _inventory{
    ARMOR   armor[MAX_ARMOR];
    WEAPONS weapons[MAX_WEAPON];
} INVENTORY;
and
typedef struct _player{
    INVENTORY   inventory;
} PLAYER;
Access is in the normal way using '.'.
However, if you don't want to limit the size of your inventory list then you
could use a linked list.
I hope I've been of some help to you Richard.
John.

assistant: In a message dated 03-29-98, Herman Schonfeld said to David Noon about
Qsort-ing A Struct
Hi Herman,
[snip]
Yes.
Not necessarily.
Radix sort is a "bit fiddling" variant of distribution counting.
Consequently, it is unsuitable for memory-constrained environments. Worse
still, its use of bit patterns can make it endian dependent. Since I work on
both big-endian and little-endian CPU's, it compromises portability. Where
radix sort really shines is when the key for comparison is short. This also
eliminates endian problems, as the keys can be manipulated in registers.
Radix sorting suffers some serious problems when the distribution of keys is
not widely spread. The bit-based comparisons go faster when the keys are
different. The more duplicates, the worse it runs.
There is also the radix exchange sort, which uses a similar comparison
technique to radix sort, but is based on Quicksort. It even has the 2
recursions of Quicksort. Again, the bit fiddling nature of the comparisons
makes it more suitable to short keys than to long ones. In that context, it
is faster than [original] Quicksort.
For sorting arrays of integers, floats or doubles, all the above pitfalls
can be avoided simply by using Shellsort, which is what I do.
Moreover, the running times for Quicksort, radix exchange and radix sort are
asymptotically O(n log n), but the asymptote is not always reached. The
running time for Shellsort [as posted in the C_PlusPlus echo] is at most O(n
sqrt n), and more typically O(n log n). Hence, the performance of Shellsort
is likely no worse than Quicksort or either of the radix algorithms, and is
often better for the types of arrays I mentioned above.
