fstrcmpi(3)

💖 fstrcmpi — like, the fuzzy string comparison one 💖

okay bestie, so this is a page from the Library Functions Manual, and today we're learning about fstrcmpi(3). it's giving "are these two strings kinda the same" energy and honestly? obsessed. 🦋

---

✨ NAME ✨

fstrcmpi — fuzzy comparison of two strings 🌸

---

✨ SYNOPSIS ✨

#include <fstrcmp.h>
#define FSTRCMPI_IDENTICAL
#define FSTRCMPI_THRESHOLD
#define FSTRCMPI_ERROR
int fstrcmpi(const char *string1, const char *string2);

---

✨ DESCRIPTION ✨

so the fstrcmpi() function compares two strings, string1 and string2. that's it. that's the whole vibe. 💅

---

✨ RETURN VALUE ✨

the fstrcmpi function hands back an int that's somewhere between 0 and FSTRCMPI_IDENTICAL. here's the tea:

• 0 — the strings are utterly un-alike. like, not even a little. 💀
• FSTRCMPI_IDENTICAL — the strings are identical, periodt. 👑
• more than FSTRCMPI_THRESHOLD — and btw FSTRCMPI_THRESHOLD lies somewhere between 0 and FSTRCMPI_IDENTICAL — would be considered "similar" by most people. 🫶
• FSTRCMPI_ERROR — which is always negative, btw — means a malloc(3) failure happened. 😭

no cap, that negative return is your signal that memory said "not today."

and here's the lore, bestie: the comparison code is derived from the fuzzy comparison functions in GNU Gettext 0.17. and those GNU Gettext comparison functions were, in turn, derived from GNU Diff 2.7. it's giving generational talent. 🧚
