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 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', '\n', '\r', '\t', '\v'.

RETURN VALUE

       The  iswspace  function  returns  non-zero if wc is a wide character belonging to the wide
       character class "space". Otherwise it returns zero.

NOTES

       The behaviour of iswspace depends on the LC_CTYPE category of the current locale.
