iswblank manual

iswblank - test for whitespace wide character

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 \t.

Return Value

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

Notes

The behavior of iswblank() depends on the LC_CTYPE category of the current locale.
