SYNOPSIS

#include <wchar.h>

int iswctype(

wint_t wc,

wctype_t wc_prop);

PARAMETERS

wc Speciﬁes the wide character to be tested.

wc_prop Speciﬁes the property to be tested for.

DESCRIPTION

The iswctype() function tests the wide character speciﬁed by the wc parameter to determine if it

has the property speciﬁed by the wc_prop parameter. The wctype( ) function associates a charac-

ter property with a wctype_t handle. Get the value of the wc_proc parameter from a call to

wctype() before using it in a call to iswctype().

NOTES

The iswctype() function is deﬁned for the wide-character null and for values in the character

range of the current code set deﬁned in the current locale.

RETURN VALUES

If the wc parameter has the property speciﬁed by the wc_prop parameter, the iswctype() function

returns a nonzero value. If the value speciﬁed by the wc parameter does not have the property

speciﬁed by the wc_prop parameter, the iswctype() function returns a value of 0 (zero). If the

value speciﬁed by the wc parameter is not in the function’s domain, the result is undeﬁned. If the

value speciﬁed by the wc_prop parameter is not valid, the result is undeﬁned.

The value of the wctype parameter can be invalid because it has not obtained by a call to the

wctype() function, or it can be invalidated by an intervening call to the setlocale() function that

has affected the LC_CTYPE environment variable.
