iswpunct - test for punctuation or symbolic wide character
The iswpunct() function is the wide-character equivalent of the ispunct(3) function. It tests whether wc is a wide character belonging to the wide-character class punct.
The wide-character class punct is a subclass of the wide-character class graph, and therefore also a subclass of the wide-character class print.
The wide-character class punct is disjoint from the wide-character class alnum and therefore also disjoint from its subclasses alpha, upper, lower, digit, xdigit.
Being a subclass of the wide-character class print, the wide-charac- ter class punct is disjoint from the wide-character class cntrl.
Being a subclass of the wide-character class graph, the wide-charac- ter class punct is disjoint from the wide-character class space and its subclass blank.
The iswpunct() function returns nonzero if wc is a wide character belonging to the wide-character class punct.
Otherwise, it returns zero.
The behavior of iswpunct() depends on the LC_CTYPE category of the current locale.
This function's name is a misnomer when dealing with Unicode characters, because the wide-character class punct contains both punctuation characters and symbol (math, currency, etc.) characters.
