iswspace - test for whitespace wide character

  #include <wctype.h>

  int iswspace(wint_t wc);

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’.

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

For an explanation of the terms used in this section, see *attributes*(7).

POSIX.1-2001, POSIX.1-2008, C99.

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