WCTYPE.H(3HEAD)WCTYPE.H(3HEAD)NAME
wctype.h, wctype - wide-character classification and mapping utilities
SYNOPSIS
#include <wctype.h>
DESCRIPTION
The <wctype.h> header defines the following types:
wint_t
As described in <wchar.h>.
wctrans_t
A scalar type that can hold values that represent locale-
specific character mappings.
wctype_t
As described in <wchar.h>.
The <wctype.h> header defines the following macro name:
WEOF
Constant expression of type wint_t that is returned by several
MSE functions to indicate end-of-file.
For all functions described in this header that accept an argument of
type wint_t, the value is representable as a wchar _t or equals the
value of WEOF. If this argument has any other value, the behavior is
undefined.
The behavior of these functions is affected by the LC_CTYPE category of
the current locale.
Inclusion of the <wctype.h> header can make visible all symbols from
the headers <ctype.h>, <stdarg.h>, <stddef.h>, <stdio.h>, <stdlib.h>,
<string.h>, <time.h>, and <wchar.h>.
