| 17 | .SH NAME | |
| 18 | iswgraph \- test for graphic wide character | |
| 19 | .SH SYNOPSIS | |
| 20 | .nf | |
| 21 | .B #include <wctype.h> | |
| 22 | .sp | |
| 23 | .BI "int iswgraph(wint_t " wc ); | |
| 24 | .fi | |
| 25 | .SH DESCRIPTION | |
| 60a90ecd MK |
26 | The |
| 27 | .BR iswgraph () | |
| 28 | function is the wide-character equivalent of the | |
| 29 | .BR isgraph (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 "graph". |
| fea681da | 35 | .PP |
| d0f17b57 | 36 | The wide-character class "graph" is a subclass of the wide-character class |
| fea681da MK |
37 | "print". |
| 38 | .PP | |
| d0f17b57 MK |
39 | Being a subclass of the wide-character class "print", |
| 40 | the wide-character class | |
| 41 | "graph" is disjoint from the wide-character class "cntrl". | |
| fea681da | 42 | .PP |
| d0f17b57 | 43 | The wide-character class "graph" is disjoint from the wide-character class |
| fea681da MK |
44 | "space" and therefore also disjoint from its subclass "blank". |
| 45 | .\" Note: UNIX98 (susv2/xbd/locale.html) says that "graph" and "space" may | |
| 68e1685c | 46 | .\" have characters in common, except U+0020. But C99 (ISO/IEC 9899:1999 |
| fea681da MK |
47 | .\" section 7.25.2.1.10) says that "space" and "graph" are disjoint. |
| 48 | .PP | |
| d0f17b57 MK |
49 | The wide-character class "graph" contains all the wide characters from the |
| 50 | wide-character class "print" except the space character. | |
| 1c44bd5b | 51 | It therefore contains |
| d0f17b57 | 52 | the wide-character classes "alnum" and "punct". |
| 47297adb | 53 | .SH RETURN VALUE |
| 60a90ecd MK |
54 | The |
| 55 | .BR iswgraph () | |
| c7094399 | 56 | function returns nonzero |
| 35cfd378 MK |
57 | if |
| 58 | .I wc | |
| 59 | is a wide character | |
| d0f17b57 | 60 | belonging to the wide-character class "graph". |
| c13182ef | 61 | Otherwise it returns zero. |
| 47297adb | 62 | .SH CONFORMING TO |
| 68e1685c | 63 | C99. |
| fea681da | 64 | .SH NOTES |
| d9bfdb9c | 65 | The behavior of |
| 60a90ecd | 66 | .BR iswgraph () |
| 1274071a MK |
67 | depends on the |
| 68 | .B LC_CTYPE | |
| 69 | category of the | |
| fea681da | 70 | current locale. |
