ignoring or blocking the SIGTTIN signal or the process group of the process is
orphaned.
[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 multi-byte 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().
AUTHOR
getwc() was developed by OSF and HP.
