iswspace() -- tests if wide character is a white space character

SYNOPSIS

#include <wctype.h>

int iswspace(wint_t wc);

DESCRIPTION

The iswspace() function tests for any wide character that corresponds to a locale-specific set of wide characters for which none of iswalnum(), iswgraph(), or iswpunct() are true.

The behavior of the iswspace() function is affected by the current locale. To modify the behavior, change the LC_CTYPE category in setlocale(), that is, setlocale(LC_CTYPE, newlocale).

PARAMETERS

wc: Is a wide character code corresponding to a valid character in the current locale or the value of the macro WEOF.

RETURN VALUES

The iswspace() function returns non-zero for true and zero for false. If the parameter is not in the domain of the function, the behavior is undefined.
