The actual SDL fix was even simpler, they now just check if the mtime of the /dev/input directory changed: https://github.com/spurious/SDL-mirror/commit/59728f9802c786...

Ah, but are /dev/input entries reusable? Let's say you have /dev/input/event{0,10}, event5 is a USB keyboard, you unplug it, I assume event5 goes away. But then you plug in a controller, does this get mapped to event11, or does event5 get reused? Is the behaviour reliable in all versions of linux? You might argue that metadata should do the trick, but in my experience, on device files, anything beyond read/write is a crapshoot, whether metadata makes any sense is basically a roll of the dice. So if you have to open device files in order to check their identity, you might as well skip the identity bit and just check if you're a gamepad. edit: per charcircuit's comment below, it looks like the metadata of /dev/input at least are considered reliable, and this was used to mitigate the issue by checking the mtime of /dev/input itself against a

From the description of the problem (a freeze every 3 seconds) I knew exactly what it was. You can fix it by simply upgrading SDL as they fixed this bug 2 years ago. https://github.com/spurious/SDL-mirror/commit/59728f9802c786...

What kind of license is it? Any possibility of ISC / MIT / BSD? Nice to see CMake! And also nice to see an effort to make something lighter than glib. It may be worth looking at BSD's base system in /usr/src to see code you can use as a reference, or add in a generic way. Take a look at #ifdef in ISC/MIT/BSD applications to see if you can port it in to offer portable functions. Hm, examples: https://github.com/tmux/tmux/blob/master/compat.h -> https://github.com/tmux/tmux/tree/master/compat For inspiration, all SDL2 is a cross-platform wrapper which probably has chunks that may be useful: https://github.com/spurious/SDL-mirror/tree/master/src, SDL_net: https://hg.libsdl.org/SDL_net/file/c5b3c4171459 Maybe the above is relevant / helpful / an inspiration. We need a lite, portable glib alternative. I'm guessing it must be hard to do. I wish

The Cocoa implementation of SDL 2 uses plain Objective-C to access Apple's APIs: https://github.com/spurious/SDL-mirror/tree/master/src/video... I couldn't find a call to objc_msgSend in other (.c) files using GitHub's code search. Objective-C and C/C++ are perfectly interoperable, there's rarely a reason to use the verbose and error-prone C API to call into Objective-C. The .m file extension is not related to Mach: https://stackoverflow.com/a/652266
