iswgraph(), iswgraph_l()

tests if wide character is printable (and not space) 

Function

SYNOPSIS

#include <wctype.h>

int iswgraph(wint_t wc);

int iswgraph_l(wint_t wc, locale_t locale);

DESCRIPTION

The iswgraph() function tests for any wide character for which iswprint() is true and iswspace() is false.

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

iswgraph_l() behaves in the same way as iswgraph() 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 iswgraph() and iswgraph_() functions return non-zero for true and zero for false. If the parameter is not in the domain of the function, or locale is invalid, the behavior is undefined.

CONFORMANCE

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