11 | SYNOPSIS |
---|
12 | #include <wctype.h> |
---|
13 | int iswctype(wint_t <[c]>, wctype_t <[desc]>); |
---|
14 | |
---|
15 | #include <wctype.h> |
---|
16 | int iswctype_l(wint_t <[c]>, wctype_t <[desc]>, locale_t <[locale]>); |
---|
17 | |
---|
18 | DESCRIPTION |
---|
19 | <<iswctype>> is a function which classifies wide-character values using the |
---|
20 | wide-character test specified by <[desc]>. |
---|
21 | |
---|
22 | <<iswctype_l>> is like <<iswctype>> but performs the check based on the |
---|
23 | locale specified by the locale object locale. If <[locale]> is |
---|
24 | LC_GLOBAL_LOCALE or not a valid locale object, the behaviour is undefined. |
---|
25 | |
---|
26 | RETURNS |
---|
27 | <<iswctype>>, <<iswctype_l>> return non-zero if and only if <[c]> matches |
---|
28 | the test specified by <[desc]>. If <[desc]> is unknown, zero is returned. |
---|
29 | |
---|
30 | PORTABILITY |
---|
31 | <<iswctype>> is C99. |
---|
32 | <<iswctype_l>> is POSIX-1.2008. |
---|
33 | |
---|
34 | No supporting OS subroutines are required. |
