25 | .SH DESCRIPTION | |
60a90ecd MK |
26 | The |
27 | .BR iswpunct () | |
28 | function is the wide-character equivalent of the | |
29 | .BR ispunct (3) | |
30 | function. | |
35cfd378 MK |
31 | It tests whether |
32 | .I wc | |
33 | is a wide character | |
d0f17b57 | 34 | belonging to the wide-character class "punct". |
fea681da | 35 | .PP |
d0f17b57 MK |
36 | The wide-character class "punct" is a subclass of the wide-character class |
37 | "graph", and therefore also a subclass of the wide-character class "print". | |
fea681da | 38 | .PP |
d0f17b57 | 39 | The wide-character class "punct" is disjoint from the wide-character class |
fea681da MK |
40 | "alnum" and therefore also disjoint from its subclasses "alpha", "upper", |
41 | "lower", "digit", "xdigit". | |
42 | .PP | |
d0f17b57 MK |
43 | Being a subclass of the wide-character class "print", |
44 | the wide-character class | |
45 | "punct" is disjoint from the wide-character class "cntrl". | |
fea681da | 46 | .PP |
d0f17b57 MK |
47 | Being a subclass of the wide-character class "graph", |
48 | the wide-character class | |
49 | "punct" is disjoint from the wide-character class "space" and its subclass | |
fea681da | 50 | "blank". |
47297adb | 51 | .SH RETURN VALUE |
60a90ecd MK |
52 | The |
53 | .BR iswpunct () | |
c7094399 | 54 | function returns nonzero |
35cfd378 MK |
55 | if |
56 | .I wc | |
57 | is a wide-character | |
d0f17b57 | 58 | belonging to the wide-character class "punct". |
2b9b829d | 59 | Otherwise, it returns zero. |

fea681da | 74 | .SH NOTES |
d9bfdb9c | 75 | The behavior of |
60a90ecd | 76 | .BR iswpunct () |
1274071a MK |
77 | depends on the |
78 | .B LC_CTYPE | |
79 | category of the | |
fea681da MK |
80 | current locale. |
81 | .PP | |
82 | This function's name is a misnomer when dealing with Unicode characters, | |
d0f17b57 | 83 | because the wide-character class "punct" contains both punctuation characters |
fea681da | 84 | and symbol (math, currency, etc.) characters. |
