Hi All,
I have some software that currently loads database tables into sorted arrays
in memory to be binary searched by processes. (Long story as to why it does
this..)
Each process must either read the data from the in memory array or from the
database itself if the table is too large to be loaded into memory. (2GB is
usually the limit because the array is indexed by a 32 bit signed integer.
I have never had one of these tables go over...

HI,
I am writing a an ATL COM component (a "dll" file).
This file calls an executable. That executable is created from the "C" language.
(Compiled on Windows platform. Using Microsoft Visual Studio to write the "C" code)
This executable has to share some data with the dll. So, the shared memory
is the best solution. But I don't know how to create a shared memory in "C".
Any inputs on this would be of great help

Oh wise readers of comp.lang.python,
Lend a newbie your ears. I have read several old articles from this
group about memory mapping and interprocess communication and have
Googled the sh** out of the internet, but have not found sufficient to
answer my questions.
Suppose that I am writing a ray tracer in Python. Well, perhaps not a
ray tracer. Suppose that I am writing a ray tracer that has to update
sixty times a second (Ignore...

Hi,
Is there a concept of shared named memory in .NET to allow multiple program
use the name and then set/retrieve values?
Thank you,

hi, i'm new to this list and new to python as well.
i have a question on the memory mapped file ability python has. when i
use a mmap on a file, will it copy the whole thing to ram or just
whatever part of it i'm working on? basically, i'm wondering if it would
be ok for me to have multiple mmap's open on very large files as i read
or write from them.

I have come across the application of placement new in memory mapped
i/o in a number of books.I am not able to understand it completely, may
be becaues of my lack of knowledge with memory mapped i/o.In my
understanding it is a system where I/O devices are treated as memory
locations and are addressed using same number of address lines.How an
object placed at a specific location makes a difference to this?Some
body pls clarify?

I'm an old Win32 guy, so I may be completely off-base here, but is there any
support for Memory-mapped files in C#?
I'm actually trying to get around a limitation with Windows Authorization
Manager. Right now, the security information contained in AzMan is either
stored in Active Directory or an XML file. I'd like to be able to store it
in a database, and populate a memory-mapped file (or it's equivalent) from
the DB when the file is...

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,...
