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
