ispunct returns a non-zero value for any printable character that is not a space character or a character for which isalnum is true. iswpunct returns a non-zero value for any printable wide character that is neither the space wide character nor a wide character for which iswalnum is true. Each of these routines returns 0 if c does not satisfy the test condition.
The result of the test condition for the ispunct function depends on the LC_CTYPE category setting of the current locale; see setlocale for more information. For iswpunct, the result of the test condition is independent of locale.
