NAME
       iswspace - test for whitespace wide character

SYNOPSIS
       #include <wctype.h>

       int iswspace(wint_t wc);

DESCRIPTION
       The  iswspace() function is the wide-character equivalent of the isspace(3) function.  It tests whether wc is a wide character belonging to
       the wide-character class "space".

       The wide-character class "space" is disjoint from the wide-character class "graph" and therefore also disjoint from its subclasses "alnum",
       "alpha", "upper", "lower", "digit", "xdigit", "punct".

       The wide-character class "space" contains the wide-character class "blank".

       The wide-character class "space" always contains at least the space character and the control characters 'f', '
', '
', '	', 'v'.

RETURN VALUE
       The  iswspace()	function  returns  nonzero  if wc is a wide character belonging to the wide-character class "space".  Otherwise it returns
       zero.

CONFORMING TO
       C99.

NOTES
       The behavior of iswspace() depends on the LC_CTYPE category of the current locale.
