| 18 | .nf | |
| 19 | .B #include <wctype.h> | |

| 23 | .SH DESCRIPTION | |
| 60a90ecd MK |
24 | The |
| 25 | .BR iswpunct () | |
| 26 | function is the wide-character equivalent of the | |
| 27 | .BR ispunct (3) | |
| 28 | function. | |
| 35cfd378 MK |
29 | It tests whether |
| 30 | .I wc | |
| 31 | is a wide character | |
| d0f17b57 | 32 | belonging to the wide-character class "punct". |
| fea681da | 33 | .PP |
| d0f17b57 MK |
34 | The wide-character class "punct" is a subclass of the wide-character class |
| 35 | "graph", and therefore also a subclass of the wide-character class "print". | |
| fea681da | 36 | .PP |
| d0f17b57 | 37 | The wide-character class "punct" is disjoint from the wide-character class |
| fea681da MK |
38 | "alnum" and therefore also disjoint from its subclasses "alpha", "upper", |
| 39 | "lower", "digit", "xdigit". | |
| 40 | .PP | |
| d0f17b57 MK |
41 | Being a subclass of the wide-character class "print", |
| 42 | the wide-character class | |
| 43 | "punct" is disjoint from the wide-character class "cntrl". | |
| fea681da | 44 | .PP |
| d0f17b57 MK |
45 | Being a subclass of the wide-character class "graph", |
| 46 | the wide-character class | |
| 47 | "punct" is disjoint from the wide-character class "space" and its subclass | |
| fea681da | 48 | "blank". |
| 47297adb | 49 | .SH RETURN VALUE |
| 60a90ecd MK |
50 | The |
| 51 | .BR iswpunct () | |
| c7094399 | 52 | function returns nonzero |
| 35cfd378 MK |
53 | if |
| 54 | .I wc | |
| 55 | is a wide-character | |
| d0f17b57 | 56 | belonging to the wide-character class "punct". |
| 2b9b829d | 57 | Otherwise, it returns zero. |

| fea681da | 77 | .SH NOTES |
| d9bfdb9c | 78 | The behavior of |
| 60a90ecd | 79 | .BR iswpunct () |
| 1274071a MK |
80 | depends on the |
| 81 | .B LC_CTYPE | |
| 82 | category of the | |
| fea681da MK |
83 | current locale. |
| 84 | .PP | |
| 85 | This function's name is a misnomer when dealing with Unicode characters, | |
| d0f17b57 | 86 | because the wide-character class "punct" contains both punctuation characters |
| fea681da | 87 | and symbol (math, currency, etc.) characters. |
