iswspace (3)

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