Hello,
I see that it is possible to use mmapfile.pyd of win32all. The same is
mentioned in http://www.python.org/windows/win32/#mmapfile.
Unfortunately I could not trace any example using mmapfile.
Any example or link to an example will be of help. I am interested to
learn how to achieve efficient sharing of data between separate
processes using mmapfile.

Hi, I don't seem to find any c# methods for memory mapped file. Does C# have
any? Or it is using different name? Thanks.

I have following structure in c++.
typedef struct MMF_result_struct
{
int action;
char text;
int cols,rows;
int month,day,year;
} MMF_result;
Now this structure is shared between C++ and C# using memory mapped file. We already have C++ code for handling memory mapped file. I am working on converting code for memory mapped file in C#. Now I have to pass pointer to the above structure. I converted this structure to C# as follows:

Hi !
I'm doing application with memory mapped file handling. I use mmf to change
data between applications. Is dllimport the only way to use those mmf
functions in VB.Net? In the application I have multiple threads which all
map mmf, is there anyway to "lock" mmf to prevent simultanous writes?
I don't know if it is wise to use mmf in .Net application, but I haven't
found anything so smooth&quick way to change data between assemblies.

*Situation* *one*:
I want to have an in memory counter that all users of the webservice could

Is there a way in C++ to have a file stream which is directly mapped to
memory(virtual memory) without actually having to create a file and
then memory mapping that file using system dependent calls?
I need this because I don't want to create a regular file on disk
(reasons for which are many , say directory permissions ), but being a
file pointer, someone can use that pointer as a regular file descriptor
for reading and writing.

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 there,
I am seeking a fastest way to load a BIG string and parse it as a
given format. I have a extern function which return a (char *)string in
BIG size. Now, I am going to parse it with a iterator as following
char *str = return_a_big_size_str();
istringstream ss(string(str), istringstream::in);
istreambuf_iterator<char> bit(ss), eit;
parsing(bit, eit);

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.

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...

Overview:
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,...
