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

   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

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