NAME

wchar.h, wchar - wide-character handling
 

SYNOPSIS

#include <wchar.h>

DESCRIPTION

The <wchar.h> header defines the following types:

wchar_t

As described in <stddef.h>.

wint_t

An integer type capable of storing any valid value of wchar_t or WEOF.

wctype_t

A scalar type of a data object that can hold values which represent locale-specific character classification.

mbstate_t

An object type other than an array type that can hold the conversion state information necessary to convert between sequences of (possibly multi-byte) characters and wide characters. If a codeset is being used such that an mbstate_t needs to preserve more than two levels of reserved state, the results are unspecified.

FILE

As described in <stdio.h>.

size_t

As described in <stddef.h>.

va_list

As described in <stdarg.h>.

The implementation supports one or more programming environments in which the width of wint_t is no greater than the width of type long. The names of these programming environments can be obtained using the confstr(3C) function or the getconf(1) utility.

The <wchar.h> header defines the following macros:

WCHAR_MAX

The maximum value representable by an object of type wchar_t.

WCHAR_MIN

The minimum value representable by an object of type wchar_t.

WEOF

Constant expression of type wint_t that is returned by several WP functions to indicate end-of-file.

NULL

As described in <stddef.h>.

The tag tm is declared as naming an incomplete structure type, the contents of which are described in the header <time.h>.

Inclusion of the <wchar.h> header can make visible all symbols from the headers <ctype.h>, <string.h>, <stdarg.h>, <stddef.h>, <stdio.h>, <stdlib.h>, and <time.h>.
