Here's a Scam I wouldn't believe.

I have a Virus on my PC named W32,NETSKY.P@MM!ENC. The reason I know =
it's there is my SYMANTEC Virus Software (Norton AntiVirus) lets me know =
everytime I sign on.

Well to make a long story short, I contacted Symantec who will remove it =
if I Pay an additional $38.00.

This seems pretty strange, because Symantec (Norton) is the software =
that allowed it to be copied to my PC.

I also did a complete Scan of my PC and was advised by Symantec that =
there was no Virus.

Maybe there isn't but Symantec still wants to charge me for removing it! =
Who knows, maybe Symantec put it on my PC.


Everyone have a Great day.

William

NOW YOU might guess what this is all about

I was hoping to change  my email address due spam, but it did not work I
will try better later I must go I am getting late now

I was wondering how to use the code profiler. I turned it on in compiling. =
When I executed my program, it spat out a .out file. Is the code profile in=

The (almost) only difference between opening a stream as binary or text is
that newline is encoded different on different OS, and in text mode, the
runtime library will auto-convert newline characters on read/write.

Some runtime libraries will also be affected by end-of-file characters,
i.e. if file is opened in text mode, they will stop reading when a
end-of-file character is found. In binary mode, there are no end-of-file
characters, and the file ends when the total number of available
characters has been read, i.e. the full size of the input file.

fread/fwrite are used to read/write buffers. These can contain binary
data, or they can contain normal text data generated with sprintf() or
parsed with sscanf() or similar. It is always up to the programmer to
know/decide if a file is binary or ascii, and use corresponding methods to
extract numbers and text from the file.

If the file is binary, you can use fread() to read a number directly into
a variable with (note not so portable because of size of an int, and byte
order between different architectures):
int n;
fread(&n,sizeof(n),1,f);

If the file is storing the data in ascii format, you can use fscanf() to
parse data directly from the file, or fgets() to read a line of text and
then extract data with atoi(), sscanf() etc or you can read a block of
data with fread() and then manually check for newline charcters etc with
strchr() or similar.

When writing binary data to file (or reading back) it is almost often best
to treat the binary file as a stream of bytes and have the code itself
split a binary integer into byte values to read/write. This assures that
it is possible to move the binary file between machines of different
architecture. The exception is for temporary files that you know never
will be moved between machines.

Example code to read/write binary data a bit more protable might look
like:

int write32(unsigned n) {
    unsigned char buf[4];
    buf[0] = (unsigned char)n;
    buf[1] = (unsigned char)(n >> 8);
    buf[2] = (unsigned char)(n >> 16);
    buf[3] = (unsigned char)(n >> 24);
    return fwrite(buf,4,1,f) == 4;
}

int read32(unsigned& n) {
    unsigned char buf[4];
    unsigned tmp;
    if (fread(buf,4,1,f) != 4) return 0;
    tmp = buf[0];
    tmp += ((unsigned)buf[1]) << 8;
    tmp += ((unsigned)buf[2]) << 16;
    tmp += ((unsigned)buf[3]) << 24;
    n = tmp;
    return 1;
}

This assumes a 32-bit architecture, and the file opened in binary mode.
Using a 64-bit processor with a 64-bit OS, the file will be 8 bytes large.
If the file wasn't opened in binary mode, and i had a binary value looking
like a newline, the runtime library would - depending on platform -
convert the binary data into garbage.

For example, the value 10 should be written as 0x0A, 0x00, 0x00, 0x00 on a
32-bit Intel. In text mode on a Windows machine it will be written as
0x0D, 0x0A, 0x00, 0x00, 0x00 because 0x0A = '\n' and 0x0D = '\r'. The
output file got a CR + LF line break.

The danger here is that Unix machines doesn't do any text conversion, so
on Unix, the source code doesn't need to specify a binary or ascii
conversion to work correctly. When such code is ported to Windows, it
will fail unless the fopen() calls are fixed.

Correct. And if you opened the file in text mode, some integers will have
a binary representation that will look like newline charactesr - as
mentioned above - resulting in a file that no program can correctly read
back.

Assume that the file was written correctly and contained an integer
looking like:
0x0D 0x0A 0x00 0x00 xx xx xx xx
which represents the value 13 + 10*256 = 2573 on a 32-bit Intel.

When trying to read the file - but opening the file in text mode - the
program will instead read:

0x0A 0x00 0x00 xx

i.e. the input file will be too short, and we either can't load enough
bytes or we will load an incorrect integer because some of the bytes in
the integer comes from the following data in the file.

Correct!

> (except newline of course!)???

There are no other conversions. However, on some systems, there is the
possibility of a end-of-file character stopping the read early. There
are ancient OS that doesn't keep track of exact file sizes - just number
of blocks.

Dear Per Westermark,

Thanks for your answer. It was really amazing ! But that caused a
question.
Do you mean that the ONLY, ONLY, and ONLY difference between text
streams and binary streams is the way that they handle NEWLINE ?????
Before I read your mail ,I used to consider that the difference is
the way that numbers are processed.

Imagine we have:

int i=3D12;
fprintf(file,"%i",i);

As you know,the result file will have 2 bytes because "12" contains
only 2 ASCII characters.In other words,the number 12 is first stringized
and then it is into the file. But assume we use

int i=3D12;
fwrite(&i,sizeof(int),1,file);

the made file will be 4 bytes long since integers consume 4 bytes.And
of course, it is impossible to read this file using a text editor
because the BINARY format of "12" is used and the number is not stringize=
d.

By reading what you said I'm getting to realized that the idea I had,
was wrong and how numbers are handled is not related to the type of
streams but to the function.
And if so, is there any other character change in a text stream
(except newline of course!)???

Thanks,

Don't know what you are talking about.

Test with the following source:

#include <stdio.h>

int main() {
    FILE *f;
    f = fopen("test.bin","wb");
    if (f) {
        fprintf(f,"test\n\n\n");
        fwrite("test\n\n\n",1,7,f);
        fclose(f);
    }
    f = fopen("test.txt","wt");
    if (f) {
        fprintf(f,"test\n\n\n");
        fwrite("test\n\n\n",1,7,f);
        fclose(f);
    }
    return 0;
}

Using MinGW 3.4.2 on WinXP gives:

2006-07-12  00:23                14 test.bin
2006-07-12  00:23                20 test.txt

The text file is 6 bytes larger, as expected.

Note that if same source is run on Linux, the result will be:

-rw-r--r--  1 pwm pwm      14 2006-07-12 00:25 test.txt
-rw-r--r--  1 pwm pwm      14 2006-07-12 00:25 test.bin

Same size as expected, since the text format uses a single-character
newline sequence on unix systems.

Both fprintf() and fwrite() will be affected by file opening mode when
using MSDOS or Windows compiler.

Hi,

I'm installing a GTK package to Dev-Cpp. Problem is, the package has entered
all the files like *include/gtk-2.0/gtk/gtk.h*. All the files in the package
has entered in their include lines only *gtk/gtk.h*. I can change MY files
to the whole thing(that is *gtk-2.0/gtk/gtk.h*, since include/ is not
needed), but there's alot of header files and anyway it seems like a stupid
idea to change them all(even if I could). So's, I suppose there should be
some way of dealing with this without changing the name? Setting in the
Compiler Options, perhaps? That's as far as I can guess, ANY answer would be
greatly appreciated(No, not any, but you get my point).

Hello,

     It is OS dependent.  Under most if not all Unix there is no
difference.

-Robert

hi,

I've noticed that fwrite() writes data in binary format and fprintf()
writes data in text format regardless to the mode I use in fopen() to
open the file.
In this situation, what the mode argument of fopen() readlly does????
I've examined this, with DEV-C++ and Digital Mars compilers and both
have produced a same result.

Thanx,
