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