GETWCHAR(3)                POSIX Programmer's Manual               GETWCHAR(3)



PROLOG
       This manual page is part of the POSIX Programmer's Manual.  The OS
       implementation of this interface may differ (consult the corresponding
       OS manual page for details of OS behavior), or the interface may not be
       implemented on OS.

NAME
       getwchar -- get a wide character from a stdin stream

SYNOPSIS
       #include <wchar.h>

       wint_t getwchar(void);

DESCRIPTION
       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 POSIX.1-2017
       defers to the ISO C standard.

       The getwchar() function shall be equivalent to getwc(stdin).

RETURN VALUE
       Refer to fgetwc().

ERRORS
       Refer to fgetwc().

       The following sections are informative.

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.
