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 aq\faq, aq\naq, aq\raq, aq\taq, aq\vaq.  

RETURN VALUE

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