okay so this is isphonogram(3), coming at you from the Library Functions Manual — yes bestie, the actual manual, not a vibe. 🫶

NAME 🎀

isphonogram, isphonogram_l — phonographic character test

LIBRARY 📚

Standard C Library (libc, -lc) — iconic, classic, linked with -lc.

SYNOPSIS ✨

#include <ctype.h>

int
isphonogram(int c);

int
isphonogram_l(int c, locale_t loc);

DESCRIPTION 🦋

The isphonogram() and isphonogram_l() functions test for a phonographic character. That's the assignment. 💖

The way that isphonogram_l() works is it takes an explicit locale argument, whereas isphonogram() uses the current global or per-thread locale. So one is all “here’s my locale, bestie,” and the other is “whatever locale we’re currently in.” Lowkey elegant. 💅

RETURN VALUES 🌸

• The isphonogram() and isphonogram_l() functions return zero if the character tests false.
• They return non-zero if the character tests true.

So: 0 = nope, non-zero = yes ma’am. No in-between, no cap. ✨

HISTORY ⭐
