This manual page is part of the POSIX Programmer’s Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.
getwc − get a wide character from a stream
#include
<stdio.h>
#include <wchar.h>
wint_t getwc(FILE *stream);
The getwc() function shall be equivalent to fgetwc(), 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.
Refer to fgetwc() .
Refer to fgetwc() .
The following sections are informative.
None.
Since it may be implemented as a macro, getwc() may treat incorrectly a stream argument with side effects. In particular, getwc(*f++) does not necessarily work as expected. Therefore, use of this function is not recommended; fgetwc() should be used instead.
None.
None.
