| 15 | .SH NAME | |
| 16 | iswpunct \- test for punctuation or symbolic wide character | |
| 17 | .SH SYNOPSIS | |
| 18 | .nf | |
| 19 | .B #include <wctype.h> | |
| 20 | .sp | |
| 21 | .BI "int iswpunct(wint_t " wc ); | |
| 22 | .fi | |
| 23 | .SH DESCRIPTION | |
| e511ffb6 | 24 | The \fBiswpunct\fP() function is the wide-character equivalent of the |
| c13182ef MK |
25 | \fBispunct\fP() function. |
| 26 | It tests whether \fIwc\fP is a wide character | |
| fea681da MK |
27 | belonging to the wide character class "punct". |
| 28 | .PP | |
| 29 | The wide character class "punct" is a subclass of the wide character class | |
| 30 | "graph", and therefore also a subclass of the wide character class "print". | |
| 31 | .PP | |
| 32 | The wide character class "punct" is disjoint from the wide character class | |
| 33 | "alnum" and therefore also disjoint from its subclasses "alpha", "upper", | |
| 34 | "lower", "digit", "xdigit". | |
| 35 | .PP | |
| 36 | Being a subclass of the wide character class "print", the wide character class | |
| 37 | "punct" is disjoint from the wide character class "cntrl". | |
| 38 | .PP | |
| 39 | Being a subclass of the wide character class "graph", the wide character class | |
| 40 | "punct" is disjoint from the wide character class "space" and its subclass | |
| 41 | "blank". | |
| 42 | .SH "RETURN VALUE" | |
| e511ffb6 | 43 | The \fBiswpunct\fP() function returns non-zero if \fIwc\fP is a wide character |
| c13182ef MK |
44 | belonging to the wide character class "punct". |
| 45 | Otherwise it returns zero. | |

| 49 | .BR ispunct (3), | |
| 50 | .BR iswctype (3) | |
| 51 | .SH NOTES | |
| e511ffb6 | 52 | The behaviour of \fBiswpunct\fP() depends on the LC_CTYPE category of the |
| fea681da MK |
53 | current locale. |
| 54 | .PP | |
| 55 | This function's name is a misnomer when dealing with Unicode characters, | |
| 56 | because the wide character class "punct" contains both punctuation characters | |
| 57 | and symbol (math, currency, etc.) characters. |
