winsdk-10 VS caprine

> Is this something you have to sign an NDA with Microsoft to get access to the headers and docs for it? Or will I find the headers hidden away in the WDK somewhere?

Turns out the header file is included in the Windows 10 SDK, as km/nthalext.h

Not the very latest version, but someone posted it on GitHub here: https://github.com/tpn/winsdk-10/blob/master/Include/10.0.16...

(You can download the multi-gigabyte Windows 10 SDK to get a more recent one.)

Still doesn't seem to be any public documentation. The header includes very detailed comments, but (as you'd expect for header file comments) they concentrate on the nitty-gritty and omit the big picture.

Searching "nthalext.h" on GitHub finds (what appears to be) source code for a number of HAL extensions, so at least there is some (third party) sample code to look at.

I'm looking at windows-rs and finding what I think is a good relevant and representative example of how EventSys is implemented, which has several IDispatch interfaces. I think this gives me a good starting point, thanks for pointing me in this direction.

I think that the author hasn't checked them all. Even this isn't checking them all.

The MUSL C library' sscanf() does not do this, but does call memchr() on limited substrings of the input string as it refills its input buffer, so it's not entirely free of this behaviour.

The sscanf() in Microsoft's C library does this because it all passes through a __stdio_common_vsscanf() function which uses length-counted rather than NUL-terminated strings internally.

The GNU C library does something similar, using a FILE structure alongside a special "operations" table, with a memchr() in the initialization.

* https://github.com/bminor/glibc/blob/master/libio/strfile.h#...

The FreeBSD C library does not use a separate "operations" table.

A glib summary is that sscanf() in these implementations has to set up state on every call that fscanf() has the luxury of keeping around over multiple calls in the FILE structure. They're setting up special nonce FILE objects for each sscanf() call, and that involves finding out how long the input string is every time.

It is food for thought. How much could life be improved if these implementations exported the way to set up these nonce FILE structures from a string, and callers used fscanf() instead of sscanf()? How many applications are scanning long strings with lots of calls to sscanf()?

If you have access to the source, package.json will have several entries for electron packages. Example.

Second was a small CSS change in a popular project, Caprine. I really had a long back and forth with the maintainer about two seemingly simple changes in a style sheet and I realized I should have been linting my code changes and I learned how to find the css elements I meant to target, it was a small step forward. https://github.com/sindresorhus/caprine/pull/1933 You can still see the remainder of a bunch of requested changes.

The second issue that I wanted to take on I wanted to upgrade from a markdown change like in my first PR. In this second PR I set out to find a small code change to make. After staring at the issue board for an hour or two I finally came across one that I was surprised was not taken. I found this open source Facebook messenger app called Caprine. This was and still is really cool to me, the opportunity to work on something that was so well put together and much larger than my previous project.

Caprine - Nezvanična Facebook Messenger aplikacija za Windows, macOS i Linux - Electron, TypeScript, CSS

I too have faced issues with it on Firefox in the past and moved on to an open source application called Caprine. Works pretty well on Windows/MacOS/Linux.

There in an open source program for Linux/Windows, called Caprine, it's on GitHub ( https://github.com/sindresorhus/caprine ). It has also a portable version for Windows on https://portapps.io , if you are on a machine that's managed by the company you work for (it's like that for me). It's like the official Messenger app for the desktop, but Messenger came out later.

There's an alternative Messenger Client : Caprine

If you absolutely have to use Facebook Messenger, perhaps you could try a free and open-source client like Caprine, which is for desktop, but there was another one for mobile as well, I just don't remember the name of it (as I personally don't use it / have the need to use Facebook Messenger).

I never actually "solved" this, but I switched to Caprine and I'm no longer having any problems. It actually works much better than the official app (it lets you send audio files, etc).
