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(3) 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.  

NOTES

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