NAME

getwc — get a wide character from a stream

SYNOPSIS

#include <stdio.h>
#include <wchar.h>

wint_t getwc(FILE *stream);

DESCRIPTION

The getwc() function is equivalent to fgetwc(3) , except that if it is implemented as a macro it may evaluate stream more than once, so the argument should never be an expression with side effects.

RETURN VALUE

Refer to fgetwc(3) .

ERRORS

Refer to fgetwc(3) .

EXAMPLES

None.

APPLICATION USAGE

Because it may be implemented as a macro, getwc() may treat incorrectly a stream argument with side effects. In particular, getwc (* f ++) will not necessarily work as expected. Therefore, use of this interface is not recommended; fgetwc(3) should be used instead.

FUTURE DIRECTIONS

None.
