DESCRIPTION
[CX] The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of IEEE Std 1003.1-2001 (“POSIX.1”) defers to the ISO C standard.
The getwchar () function shall
be equivalent to
getwc (
stdin).
RETURN VALUE

ERRORS
Refer to fgetwc(3).
EXAMPLES
None.
APPLICATION USAGE
If the wint_t value returned by
getwchar () is stored into a variable of type
wchar_t
and then compared against the wint_t macro WEOF, the
result may be incorrect. Only the wint_t type is
guaranteed to be able to represent any wide character and WEOF.
RATIONALE
None.
FUTURE DIRECTIONS
None.
