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);
DESCRIPTION
The iswblank function is the wide-character equivalent of the isblank 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 non-zero if wc is a wide character belonging to the wide character class "blank". Otherwise it returns zero.
CONFORMING TO
This function is a GNU extension.
SEE ALSO isblank(3), iswctype(3)NOTES
The behaviour of iswblank depends on the LC_CTYPE category of the current locale.
