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.
