A single line of code from a large application that somehow manages to provide an almost endless insight into the pain that its maintainers face each day.
Five years ago, someone at Adam’s company made a commit. Like all good commits, it touched 200 individual files and 3,500 lines of code, and the commit message was simply: “Fixed”.
One of those 200 files was a .h header file, declaring a long pile of function prototypes. One of them is this one. It has no implementation, and isn’t used anywhere:
Bryant E was debugging a hardware system with some embedded C code. Due to form factor considerations, there weren't a lot of physical inputs to this device, which meant what controls it had needed to be reused cleverly.
For example, there was a pushbutton. Just pushing it performed one function. Press-and-hold did another. Double click and triple click did yet more functions.
