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 isspace 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 con-
       trol 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
       ISO/ANSI C, UNIX98

SEE ALSO
       isspace(3), iswctype(3)

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