ISWBLANK

NAME

iswblank - test for whitespace wide character  

SYNOPSIS

#include <wctype.h>

int iswblank(wint_t wc);

Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

iswblank():

_XOPEN_SOURCE >= 600 || _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L;
or cc -std=c99
 

DESCRIPTION

The iswblank() function is the wide-character equivalent of the isblank(3) function. It tests whether wc is a wide character belonging to the wide-character class "blank".

The wide-character class "blank" is a subclass of the wide-character class "space".

Being a subclass of the wide-character class "space", the wide-character class "blank" 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 "blank" always contains at least the space character and the control character aq\taq.  

RETURN VALUE

The iswblank() function returns nonzero if wc is a wide character belonging to the wide-character class "blank". Otherwise, it returns zero.
