iswspace(), iswspace_l()

tests if wide character is a white space character 

Function


SYNOPSIS

#include <wctype.h>

int iswspace(wint_t wc);

int iswspace_l(wint_t wc, locale_t locale);


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).

iswspace_l() behaves in the same way as iswspace() without the _l suffix, but uses the specified locale rather than the global or per-thread locale. A locale_t is returned by newlocale().


PARAMETERS

wc 

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

locale 

Is a locale_t perhaps returned by newlocale() or LC_GLOBAL_LOCALE or 0 for the current thread locale set with uselocale().


RETURN VALUES

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


CONFORMANCE

ANSI/ISO 9899-1990/AM 1-1995.


MULTITHREAD SAFETY LEVEL
