This manual page is part of the POSIX Programmer's Manual. The
Linux implementation of this interface may differ (consult the
corresponding Linux manual page for details of Linux behavior),
or the interface may not be implemented on Linux.
Имя (Name)
wctob — wide-character to single-byte conversion
Синопсис (Synopsis)
#include <stdio.h>
#include <wchar.h>
int wctob(wint_t c);
Описание (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. This
volume of POSIX.1‐2017 defers to the ISO C standard.
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.
The behavior of this function shall be affected by the LC_CTYPE
category of the current locale.
Возвращаемое значение (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.
