getwc(3C) getwc(3C)

[EILSEQ] The data obtained from the input stream does not form a valid wide character.

Additional

errno values may be set by the underlying

read() function (see read(2)).

EXTERNAL INFLUENCES

Locale

The

LC_CTYPE category determines how wide-character conversions are done.

International Code Set Support

Single- and multibyte character code sets are supported.

WARNINGS

If the value returned by

getwc(), getwchar()

, fgetwc(),orfgetwc_unlocked()

is stored into

a type

wchar_t variable then compared against the constant

WEOF, the comparison may never succeed

because extension of a

wchar_t to a wint_t

is machine-dependent.

getwc_unlocked()

, getwchar_unlocked()

and fgetwc_unlocked()

are obsolescent inter-

faces supported only for compatibility with existing DCE applications. New multithreaded applications

should use

getwc(), getwchar() and fgetwc()
