💖 STRDIFF 💖 (that's section 3pub of the C Programmer's Manual, bestie)

okay so picture this: it's STRDIFF(3pub), straight out of the C Programmer's Manual, and it does literally one thing but it does it so well 🫶

✨ NAME ✨

strdiff — locate the first difference between two strings 🔍

🌸 SYNOPSIS 🌸

#include <publib.h>
size_t strdiff(const char *str1, const char *str2);

🦋 DESCRIPTION 🦋

so strdiff walks both strings from the very beginning and finds the first character that is different between str1 and str2. it's giving "spot the difference" but make it compiler-coded 💅

and here's the lil plot twist: the terminating zero characters are considered different. like, yes queen, '\0' counts as a difference. no cap.

👑 RETURN VALUE 👑

strdiff returns the offset of the first pair of differring characters — or, if it hits a zero character first, the offset of the first zero character it finds. either way you're getting an offset back, periodt. ✨
