Hi
I'm writing a commercial program which must be reliable. It has to do
some basic reading and writing to and from files on the hard disk,
and also to a floppy.
I have foreseen a potential problem. The program may crash
unexpectedly while writing to the file. If so, my program should
detect this during startup, and then (during startup) probably delete the
data added to the file and redo the writing operation.

Hi all!
I'm trying to extend the functionality of the file object by creating a
class that derives from file. MyFile class re-implements __init__(),
write(), writelines() and close() to augment the capabilities of file.
All works fine, except for one thing: 'print >> myfile' does not
execute Myfile.write(), it executes the file.write(). If I execute
myfile.write() explicitly, then Myfile.write() is called as expected.

This may be the wrong group but I didn't see anything for VC++ so I'm
trying here.
I have a C++ book by Deitel and Deitel that says I can use fstream
File("data.dat", ios::in | ios::out | ios::binary) to declare a file
object with read/write modes turned on for working with binary data.
I've tried this and my file is not created. The only time it is created
is when I specify ifstream or ofstream but not fstream. I've tried
removing the...

According to my ANSI book, tmpfile() creates a file with wb+ mode
(that is just writing, right?). How would one reopen it for reading?
I got the following (which works):
FILE *tmpFile = tmpfile();
/* write into tmpFile */

Hi,
It looks like the only way to get a size of a file within csharp is to
use FileInfo and the Length property. However that only returns the
number of bytes in the file which is translating properly (I have a
file that has a size of 1 KB but has 14 bytes in it so the conversion
isn't working right). Is there some method/property out there that
will get the actual size of the file? Also, would there be a method
like this that will...

Hi All,
I am writing a small tool which is supposed to fill the filesystem to a
specified percent.
For, that I need to read how much the file system is full in percent,
like the output given by df -k

Hi
The company I work for has finally woken up to data security on our field
laptops. I'm writing something in C# that will allow remote deletion of
sensitive data and I don't believe File.Delete() will be sufficient.
Is there anything in .NET that removes any remanence of the file?
If it isn't going to be easy, does anyone know of a component that I can
hook into to do the dirty work, free of otherwise?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...
