GRAPHEME_IS_TITLECASE(3)

💖 GRAPHEME_IS_TITLECASE(3) 💖

okay so bestie, this is a page from the Library Functions Manual and it's lowkey one of the cutest little checks in the whole grapheme library. let's get into it 🎀

---

✨ NAME ✨

grapheme_is_titlecase — check if codepoint array is titlecase 👑

🌸 SYNOPSIS 🌸

#include <grapheme.h>

size_t
grapheme_is_titlecase(const uint_least32_t *str, size_t len,
    size_t *caselen);

🦋 DESCRIPTION 🦋

okay so grapheme_is_titlecase() is literally the vibe check 💅 — it checks if the codepoint array str is titlecase, and then it writes the length of the matching titlecase-sequence to the integer pointed to by caselen, unless caselen is set to NULL (in which case she simply doesn't bother, respect 🫶).

and like, here's the tea on len ☕ — if len is set to SIZE_MAX (and yes, stdint.h is already included by grapheme.h, so you don't gotta do anything extra, slay), then the codepoint array src is interpreted to be NUL-terminated and processing stops when a NUL-byte is encountered. periodt. 🔥

also, for UTF-8-encoded input data you can use grapheme_is_titlecase_utf8(3) instead — she's right there, use her 🌈

⭐ RETURN VALUES ⭐

grapheme_is_titlecase() returns true if the codepoint array str is titlecase, otherwise false. that's it, that's the whole thing 💀
