wctob

Sommaire

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 multi-byte 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 internationalized programs. Internationalized programs must never distinguish single-byte and multi-byte characters.

RETURN VALUE

The wctob() function returns the single-byte representation of c, if it exists, of EOF otherwise.

CONFORMING TO

C99.

SEE ALSO

wctomb(3)

NOTES

The behaviour 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 multi-byte characters. Use the function wctomb() instead.
