33 <<iswspace>>, <<iswspace_l>>---whitespace wide character test

41 SYNOPSIS
42 #include <wctype.h>
43 int iswspace(wint_t <[c]>);
44
45 #include <wctype.h>
46 int iswspace_l(wint_t <[c]>, locale_t <[locale]>);
47
48 DESCRIPTION
49 <<iswspace>> is a function which classifies wide-character values that
50 are categorized as whitespace.
51
52 <<iswspace_l>> is like <<iswspace>> but performs the check based on the
53 locale specified by the locale object locale. If <[locale]> is
54 LC_GLOBAL_LOCALE or not a valid locale object, the behaviour is undefined.
55
56 RETURNS
57 <<iswspace>>, <<iswspace_l>> return non-zero if <[c]> is a whitespace wide character.
58
59 PORTABILITY
60 <<iswspace>> is C99.
61 <<iswspace_l>> is POSIX-1.2008.
62
63 No supporting OS subroutines are required.
