NAME

6       iswspace - test for whitespace wide character
7

SYNOPSIS

9       #include <wctype.h>
10
11       int iswspace(wint_t wc);
12

DESCRIPTION

14       The  iswspace()  function  is the wide-character equivalent of the iss‐
15       pace(3) function.  It tests whether wc is a wide character belonging to
16       the wide-character class "space".
17
18       The  wide-character  class  "space" is disjoint from the wide-character
19       class "graph" and therefore also disjoint from its subclasses  "alnum",
20       "alpha", "upper", "lower", "digit", "xdigit", "punct".
21
22       The  wide-character  class  "space"  contains  the wide-character class
23       "blank".
24
25       The wide-character class "space" always contains  at  least  the  space
26       character and the control characters '\f', '\n', '\r', '\t', '\v'.
27

RETURN VALUE

29       The  iswspace()  function  returns  nonzero  if  wc is a wide character
30       belonging to the wide-character class "space".   Otherwise  it  returns
31       zero.
32

CONFORMING TO

NOTES

37       The behavior of iswspace() depends on the LC_CTYPE category of the cur‐
38       rent locale.
