iswblank
ISWBLANK(3) Linux Programmer's Manual ISWBLANK(3)
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 ' '.
RETURN VALUE
The iswblank() function returns nonzero if wc is a wide character belonging to the wide-character class "blank". Otherwise it returns
zero.
CONFORMING TO
POSIX.1-2001.
NOTES
The behavior of iswblank() depends on the LC_CTYPE category of the current locale.

isblank(3), iswctype(3)
