ISWSPACE(3)               (2019-03-06)                ISWSPACE(3)

     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 aq\faq, aq\naq,
          aq\raq, aq\taq, aq\vaq.

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

     NOTES

          of the current locale.
