Имя (Name)

iswpunct - test for punctuation or symbolic wide character

Синопсис (Synopsis)

#include <wctype.h>

int iswpunct(wint_t wc);


Описание (Description)

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- character class "punct" is disjoint from the wide-character class "cntrl".

Being a subclass of the wide-character class "graph", the wide- character class "punct" is disjoint from the wide-character class "space" and its subclass "blank".


Возвращаемое значение (Return value)

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

Стандарты (Conforming to)

Примечание (Note)

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.
