'evening.
I'm not new to C and have been programming in it since I was 8 but
here's a strange problem I've never seen before.
When I compile a program from our C course with a windows compiler
there is no problem but when I try to compile it with a linux compiler
it complains that
a_03.c:(.text+0 x4d): warning: the `gets' function is dangerous
and should not be used.
Is linux more dangerous than windows? Where can I download a
non dangerous gets function? I have never used gets before is
there undefined behavior somewhere?
Here is a trimmed down example program from my assignment that
demonstrates the problem
#include <stdio.h>
#include <malloc.h>
void main()
{
char *string;
printf("enter string (max 2000 chars): ");
fflush(stdin);
fflush(stdout);
string = (char *)malloc(2001);
if(!string) exit(1);
gets(string);
printf("you entered: %s\n", string);
free(string);
exit(0);
}
On windows with TurboC and Lcc no error is printed. On linux with
gcc it says gets is dangerous.
Please advise my instructor says gcc is overly pedantic.

You are BOTH just giving the trolls an excuse for more bitching about

Be careful about what you say. Are you referring to me when you say
"troll"? I'm not (at least no one's ever called me that before).
You're deliberately calling a "troll" someone who isn't one and for no
reason. That makes *you* a troll.

Flash will no doubt answer for himself, but I don't believe he was
referring to you, and I'm at a loss to understand why you would assume
that he was.
Because I'm the one who posted the humorous list about "On-topic" and
"Off-topic" subjects, which may well be interpreted as someone
"bitching about topicality rules."

Antoninus Twink has posted in this thread. I wouldn't worry about
anyone calling *you* a troll.
But I'll point out that Flash didn't mention your name, yet you jumped
very quickly from asking him whether he was calling you a troll to
stating, with no apparent doubt, that he was deliberately doing so.
If you really were worried about it, you might have asked and then
waited for an answer.

Keith is correct.

It was not because of you posting that list.
To be honest I can't remember enough posts by you to have formed *any*
opinion about you. I've no idea if this is because of my bad memory or
if you have not posted enough to this group for me to have formed an
opinion.

No contradiction, according to my lights. When I was in school, I was
taught that to form an abbreviation you took the first letter of each
word, as in "BBC" for "British Broadcasting Corporation", "RAF" for "Royal
Air Force", "MCC" for "Marylebone Cricket Club", etc. (If they happened to
form a pronounceable word, then you had not only an abbreviation but also
an acronym.) But "contractio n" was a more general term that referred to a
more general shortening, not merely the taking of each first letter.

It has taken both of you for this argument to run on, so by now in
my opinion you are both just as guilty of holding a long-running
off-topic argument and for *this* group it is completely irrelevant
which if you is right or wrong.
Applause.

I see none of this in any C99 standard.

If you'd looked a little closer, you'd have found that C99's usage of the
word "abbreviate d" (which has the same root as "abbreviati on") clearly
disagrees with the way I was taught at school. (See 7.23.3.5(3) for
details.) Thus, this discussion has uncovered a flaw in the Standard! So
it seems it may conceivably have been worthwhile after all. :-)

I read an article in a book about Perl and Common Gateway Interface and it
mentioned C. It said that C could damage your computer. I don't know wether
it meant the standard or compiler issuses. I was a little upset. Well more
upset. I sent Dennis Ritchie and email. I don't know if he'll respond if he
gets it. Sometimes he does sometimes not. How can C damage your computer?

Hi !
I have important doubts about how to handle the security in asp.net
vb.net web forms. Somebody can help me?
1. If you have setting ‘validateRequest=true’ in .net framework1.1,
What can do you do to improve the security? Because although you have
validations on server side you can enter dangerous characters in a
text field, with the exception of telephone numbers or similar.

Hi
Whenever I use the gets() function, the gnu c compiler gives a
warning that it is dangerous to use gets(). Is this due to the
possibility of array overflow? Is it correct that the program flow can
be altered by giving some specific calculated inputs to gets()? How
could anyone do so once the executable binary have been generated? I
have heard many of the security problems and other bugs are due to
array overflows.

Hi,
I'm trying to mimic the IPC/messaging system of an specific OS in a
portable way by using GCC's library. The IPC system uses buffered
asynchronous messages, where any thread can send a message to any other
thread (i.e. to the "threadID") without blocking, and the receiver does
any security checks necessary.
I'm trying to implement the portable/linux version on top of
sockets/datagrams ("SOCK_DGRAM" in the local namespace), and so...
