| 15 | .SH NAME | |
| 16 | iswpunct \- test for punctuation or symbolic wide character | |

| 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. | |
| c13182ef | 29 | It tests whether \fIwc\fP is a wide character |
| d0f17b57 | 30 | belonging to the wide-character class "punct". |
| fea681da | 31 | .PP |
| d0f17b57 MK |
32 | The wide-character class "punct" is a subclass of the wide-character class |
| 33 | "graph", and therefore also a subclass of the wide-character class "print". | |
| fea681da | 34 | .PP |
| d0f17b57 | 35 | The wide-character class "punct" is disjoint from the wide-character class |
| fea681da MK |
36 | "alnum" and therefore also disjoint from its subclasses "alpha", "upper", |
| 37 | "lower", "digit", "xdigit". | |
| 38 | .PP | |
| d0f17b57 MK |
39 | Being a subclass of the wide-character class "print", |
| 40 | the wide-character class | |
| 41 | "punct" is disjoint from the wide-character class "cntrl". | |
| fea681da | 42 | .PP |
| d0f17b57 MK |
43 | Being a subclass of the wide-character class "graph", |
| 44 | the wide-character class | |
| 45 | "punct" is disjoint from the wide-character class "space" and its subclass | |
| fea681da MK |
46 | "blank". |
| 47 | .SH "RETURN VALUE" | |
| 60a90ecd MK |
48 | The |
| 49 | .BR iswpunct () | |
| c7094399 | 50 | function returns nonzero |
| d0f17b57 MK |
51 | if \fIwc\fP is a wide-character |
| 52 | belonging to the wide-character class "punct". | |
| c13182ef | 53 | Otherwise it returns zero. |
| fea681da | 54 | .SH "CONFORMING TO" |
| 68e1685c | 55 | C99. |
| fea681da | 56 | .SH NOTES |
| d9bfdb9c | 57 | The behavior of |
| 60a90ecd | 58 | .BR iswpunct () |
| 1274071a MK |
59 | depends on the |
| 60 | .B LC_CTYPE | |
| 61 | category of the | |
| fea681da MK |
62 | current locale. |
| 63 | .PP | |
| 64 | This function's name is a misnomer when dealing with Unicode characters, | |
| d0f17b57 | 65 | because the wide-character class "punct" contains both punctuation characters |
| fea681da | 66 | and symbol (math, currency, etc.) characters. |
