While java's System.in is, according to the javadocs, an InputStream, it
is in fact an instance of java.io.BufferedInputStream. Is there any way
to have unbuffered access to it without hacking the JRE? (I can do it on
my own computer, simply changing FilterInputStream's "in" field from
"protected" to "public", but then I can't distribute my program).

Is this even possible? I've found some references to specific "unbuffered"
type methods that exist in older incarnations of basic_streambuf but not in
newer ones.
Info please. :P

hi everyone,
I have a program here to test the file IO(actually output) with buffer
turned on and off. What I want to see is that there will be obvious
differece in time. Here I have an input file scales 1.1M, what I did is
just copy it to another output file(ten times). But I don't think I see
any difference. My file system is ext3, with debian
sarge(kernel-2.6.8).
Here is the main part of my program:

Hi folks.
I'm somewhat new to *nix programming and just ran into a problem. I have
to take user input from the terminal but like to constrain that to some
rules given, i.e. "numbers only" or "alphanumeric only" etc.
scanf would do, but I don't like the fact that wrong ('disallowed')
characters are visible and all that stuff. For that I need unbuffered
input. Since there seems to be no atomic function to do that I tried to
fiddle around...

I am looking to take unbuffered, unechoed input from the user.
The idea is to print "Press any key to continue" and allow the user to do just that, without having to press enter, and without having to see their character input displayed on screen.
I know I can do this with MS compilers by including conio.h, and calling getch().
However, I am looking for something that is part of the C standard library. I've searched all over, but have not...

Hi, is there any way to get unbuffered stdout/stderr without relying on
the -u flag to python or calling .flush() on each print (including
indirect hacks like replacing sys.stdout with a wrapper that succeeds
each write() with a flush())? Thanks in advance!

what is the difference between the buffered and unbuffered stream ??(e.g we say that cout is buffered and cerr is unbuffered stream) does that mean that the output sent to buffered stream have to go through a buffer (i.e a temporary storage registers) ,,
if so then what is the big deal in unbuffered stream??

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...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
