UCHAR.H(3HEAD) Headers UCHAR.H(3HEAD)
NAME
uchar.h - unicode utilities header
SYNOPSIS
#include <uchar.h>DESCRIPTION
The <
uchar.h> header provides support for the C11 Unicode utilities.
The types and functions provide means for working with data encoded as
UTF-16 and UTF-32. When working in non-Unicode locales, these types
may not represent Unicode code points.
The <
uchar.h> header defines the following types:
char16_t An unsigned integer that can represent 16-bit characters,
generally a single single UTF-16 code unit. A Unicode
code point may be one or two UTF-16 code units due to
surrogate pairs.
char32_t An unsigned integer that can represent 32-bit characters,
generally a single UTF-32 code unit.
size_t An unsigned integer that represents the size of various
objects. This can hold the result of the
sizeof operator. See also
stddef.h(3HEAD).
mbstate_t An object that holds the state for converting between
character sequences and wide characters (
wchar_t,
char16_t,
char32_t). See also,
wchar.h(3HEAD).
The <
uchar.h> header also defines the following functions which are
used to convert between
char16_t and
char32_t sequences and other
character sequences:
c16rtomb(3C) Convert
char16_t sequences to multi-byte character
sequences.
c32rtomb(3C) Convert
char32_t sequences to multi-byte character
sequences.
mbrtoc16(3C) Convert multi-byte character sequences to
char16_t sequences.
mbrtoc32(3C) Convert multi-byte character sequences to
char32_t sequences.
