WCTOB(3) Linux Programmer's Manual WCTOB(3)NAME
wctob - try to represent a wide character as a single byte
SYNOPSIS
#include <wchar.h>
int wctob(wint_t c);
DESCRIPTION
The wctob() function tests whether the multibyte representation of the
wide character c, starting in the initial state, consists of a single
byte. If so, it is returned as an unsigned char.
Never use this function. It cannot help you in writing international‐
ized programs. Internationalized programs must never distinguish sin‐
gle-byte and multibyte characters.
RETURN VALUE
The wctob() function returns the single-byte representation of c, if it
exists, of EOF otherwise.
CONFORMING TO
C99.
NOTES
The behavior of wctob() depends on the LC_CTYPE category of the current
locale.
This function should never be used. Internationalized programs must
never distinguish single-byte and multibyte characters. Use the func‐
tion wctomb(3) instead.
