NAME

       iswupper - test for an uppercase letter wide-character code

SYNOPSIS

       #include <wctype.h>

       int iswupper(wint_t wc);

DESCRIPTION

       The  iswupper() function shall test whether wc is a wide-character code
       representing a character  of  class  upper  in  the  program's  current
       locale;  see  the  Base  Definitions  volume  of  IEEE Std 1003.1-2001,
       Chapter 7, Locale.

       The wc argument is a wint_t, the value of which the  application  shall
       ensure  is  a wide-character code corresponding to a valid character in
       the current locale, or equal to the value of the  macro  WEOF.  If  the
       argument has any other value, the behavior is undefined.

RETURN VALUE

       The  iswupper()  function  shall  return non-zero if wc is an uppercase
       letter wide-character code; otherwise, it shall return 0.

ERRORS

       No errors are defined.
