Description

Macro

mbstate_t

Indicates the type for holding the necessary state of conversion between sequences of multibyte characters and wide characters.

wint_t

Indicates the type for holding extended characters.

Constant

(macro)

WEOF

Indicates the end-of-file.

Function

fwprintf

Converts the output format and outputs data to a stream.

vfwprintf

Equivalent to fwprintf with the variable argument list replaced by va_list.

swprintf

Converts the output format and writes data to an array of wide characters.

vswprintf

Equivalent to swprintf with the variable argument list replaced by va_list.

wprintf

Equivalent to fwprintf with stdout added as an argument before the specified arguments.

vwprintf

Equivalent to wprintf with the variable argument list replaced by va_list.

fwscanf

Inputs and converts data from the stream under control of the wide string and assigns it to an object.

vfwscanf <-lang=c99>

Equivalent to fwscanf with the variable argument list replaced by va_list.

swscanf

Converts data under control of the wide string and assigns it to an object.

vswscanf <-lang=c99>

Equivalent to swscanf with the variable argument list replaced by va_list.

wscanf

Equivalent to fwscanf with stdin added as an argument before the specified arguments.

vwscanf <-lang=c99>

Equivalent to wscanf with the variable argument list replaced by va_list.

fgetwc

Inputs a wide character as the wchar_t type and converts it to the wint_t type.

fgetws

Stores a sequence of wide characters in an array.

fputwc

Writes a wide character.

fputws

Writes a wide string.

fwide

Specifies the input/output unit.

getwc

Equivalent to fgetwc.

getwchar

Equivalent to getwc with stdin specified as an argument.

putwc

Equivalent to fputwc.

putwchar

Equivalent to putwc with stdout specified as the second argument.

ungetwc

Returns a wide character to a stream.

wcstod / wcstof / wcstold

These convert the initial part of a wide string to double, float, or long double representation.

wcstol / wcstoll / wcstoul / wcstoull

(wcstoll <-lang=c99>)

(wcstoull <-lang=c99>)

These convert the initial part of a wide string to long int, long long int, unsigned long int, or unsigned long long int representation.
