Adventures with \Device\Afd - test driven design
I’ve been investigating the ‘sparsely documented’ \Device\Afd interface that lies below the Winsock2 layer. Today I use a test-driven method for building some code to make using this API a little easier. Using the API In … -

Adventures with \Device\Afd - a simple client
Now that I have a reasonably easy to use event-driven socket class I can start to use it. The first thing to build is a simple client. This will connect to a server and expect that server to echo anything that is sent to it. The client will … -

Adventures with \Device\Afd - a simple server
The only difference between a client and a server is the way in which the connection is established. For a client, you create a socket and call “connect” on it. For a server, we have a socket that is “listening” for … -

Old and cranky me from 20 years ago
Back in 2004 I wrote this, I wonder why I used to make some people unhappy… I’m starting to believe that, at 37, I must now be old and cranky because to be quite honest with you; if you’re not writing code in such a way … -

MiniDumpWriteDump now mostly useless for in process use
I’ve been using the MiniDumpWriteDump() API from DbgHelp.dll for 20 years or so. It has proven to be a useful diagnostic tool, and I use it in all manner of places, including many where others may simply use an assert(). It’s a … -

The US government's view on memory safe code is not the whole story
There’s a lot of noise about how “Joe Biden’s government wants you to move away from using C++”. This is as a result of the US government releasing a report, Back to the building blocks: A path toward secure and … -

Debugging yourself...
Recently I spent quite a long time debugging a heap corruption bug. When I eventually found the issue, it was such a classic buffer overrun bug that it was actually quite laughable how long it had taken to track it down. It was just SO … -

More \Device\Afd goodness
For a while now I’ve been playing around with the low-level access to the Windows networking stack that is provided by \Device\Afd. Recently I had a comment from a reader, Matt James, who pointed me in the direction of his work over … -

Visual Studio solution files with unix line-end crash explorer...
I’ve just had to deal with a situation where Windows 11 Explorer crashes and restarts every time I browse to a particular directory. The directory contained the source to my AFD code and I somehow managed to guess at the cause and fix … -

Socket readiness without \Device\Afd
Recently, I’be been exploring socket readiness notifications on Windows using the \Device\Afd interface. My initial forays into this were from a Linux epoll direction as the use of the \Device\Afd API provides a similar interface to … -

A multi-connection AFD-based echo server
Last time I looked at way of using \Device\Afd to perform individual socket polling for readiness. This differed from the previous approach to using \Device\Afd, which batched up the sockets and issued a single poll for multiple sockets. … -

This project cannot build given the current state of the project.
I’ve been cleaning up a continuous integration build system for my cloud gaming client’s server system. The codebase is pretty big, and my build system on Windows is pretty rubbish but works… It has been getting slower …
