NAMEiswpunct - test for punctuation or symbolic wide character
#include <wctype.h>int iswpunct(wint_t wc);
DESCRIPTIONThe iswpunct() function is the wide-character equivalent of the ispunct(3) function. It tests whether wcis 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".
RETURN VALUEThe iswpunct() function returns nonzero if wcis a wide-character belonging to the wide-character class "punct". Otherwise, it returns zero.
