🌸 WCTOB(3POSIX) — the POSIX Programmer's Manual, bestie edition 🌸

okay so first things first, this page lives in the POSIX Programmer's Manual, and I need you to know that the Linux implementation of this interface may differ — so if you're on Linux, go peek at the corresponding Linux manual page for the actual tea on Linux behavior. or like… the interface might not even be implemented on Linux at all. 🙈 vibe check accordingly.

✨ PROLOG ✨

So basically: this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (fr fr, consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux. 👑

💖 NAME 💖

wctob — wide-character to single-byte conversion. it's giving glow-down, but make it intentional 💅

🦋 SYNOPSIS 🦋

#include <stdio.h>
#include <wchar.h>

int wctob(wint_t c);

🌸 DESCRIPTION 🌸

The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional — like, if they beef, it was an accident, we promise. This volume of POSIX.1‐2017 defers to the ISO C standard. periodt.

The wctob() function shall determine whether c corresponds to a member of the extended character set whose character representation is a single byte when in the initial shift state. that's the whole job. iconic of it.

The behavior of this function shall be affected by the LC_CTYPE category of the current locale. so like, locale matters, bestie — don't forget her. 🌈

⭐ RETURN VALUE ⭐

  • The wctob() function shall return EOF if c does not correspond to a character with length one in the initial shift state. 😭
  • Otherwise, it shall return the single-byte representation of that character as an unsigned char converted to int. ✨
