It tests whether \fIwc\fP is a wide character +belonging to the wide character class "punct". +.PP +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". +.PP +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". +.PP +Being a subclass of the wide character class "print", the wide character class +"punct" is disjoint from the wide character class "cntrl". +.PP +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". +.SH "RETURN VALUE" +The \fBiswpunct\fP function returns non-zero if \fIwc\fP is a wide character +belonging to the wide character class "punct". Otherwise it returns zero. +.SH "CONFORMING TO" +ISO/ANSI C, UNIX98 +.SH "SEE ALSO" +.BR ispunct (3), +.BR iswctype (3) +.SH NOTES +The behaviour of \fBiswpunct\fP depends on the LC_CTYPE category of the +current locale. +.PP +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. |
