ISWSPACE(E)         Linux Programmer's Manual         ISWSPACE(E)



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  char-
       acter 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 charac-
       ter 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
       ISO/ANSI C, UNIX98

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