| 20 | .B #include <wctype.h> | |

| 24 | .SH DESCRIPTION | |
| 60a90ecd MK |
25 | The |
| 26 | .BR iswpunct () | |
| 27 | function is the wide-character equivalent of the | |
| 28 | .BR ispunct (3) | |
| 29 | function. | |
| 35cfd378 MK |
30 | It tests whether |
| 31 | .I wc | |
| 32 | is a wide character | |
| d0f17b57 | 33 | belonging to the wide-character class "punct". |
| fea681da | 34 | .PP |
| d0f17b57 MK |
35 | The wide-character class "punct" is a subclass of the wide-character class |
| 36 | "graph", and therefore also a subclass of the wide-character class "print". | |
| fea681da | 37 | .PP |
| d0f17b57 | 38 | The wide-character class "punct" is disjoint from the wide-character class |
| fea681da MK |
39 | "alnum" and therefore also disjoint from its subclasses "alpha", "upper", |
| 40 | "lower", "digit", "xdigit". | |
| 41 | .PP | |
| d0f17b57 MK |
42 | Being a subclass of the wide-character class "print", |
| 43 | the wide-character class | |
| 44 | "punct" is disjoint from the wide-character class "cntrl". | |
| fea681da | 45 | .PP |
| d0f17b57 MK |
46 | Being a subclass of the wide-character class "graph", |
| 47 | the wide-character class | |
| 48 | "punct" is disjoint from the wide-character class "space" and its subclass | |
| fea681da | 49 | "blank". |
| 47297adb | 50 | .SH RETURN VALUE |
| 60a90ecd MK |
51 | The |
| 52 | .BR iswpunct () | |
| c7094399 | 53 | function returns nonzero |
| 35cfd378 MK |
54 | if |
| 55 | .I wc | |
| 56 | is a wide-character | |
| d0f17b57 | 57 | belonging to the wide-character class "punct". |
| 2b9b829d | 58 | Otherwise, it returns zero. |

| fea681da | 78 | .SH NOTES |
| d9bfdb9c | 79 | The behavior of |
| 60a90ecd | 80 | .BR iswpunct () |
| 1274071a MK |
81 | depends on the |
| 82 | .B LC_CTYPE | |
| 83 | category of the | |
| fea681da MK |
84 | current locale. |
| 85 | .PP | |
| 86 | This function's name is a misnomer when dealing with Unicode characters, | |
| d0f17b57 | 87 | because the wide-character class "punct" contains both punctuation characters |
| fea681da | 88 | and symbol (math, currency, etc.) characters. |
