ISWSPACE(3)		   Linux Programmer's Manual		   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 iss‐
       pace() 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.

CONFORMING TO
       C99.

SEE ALSO
       isspace(3), iswctype(3)

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