11 | SYNOPSIS |
---|
12 | #include <wctype.h> |
---|
13 | int iswalnum(wint_t <[c]>); |
---|
14 | |
---|
15 | #include <wctype.h> |
---|
16 | int iswalnum_l(wint_t <[c]>, locale_t <[locale]>); |

---|
18 | DESCRIPTION |
---|
19 | <<iswalnum>> is a function which classifies wide-character values that |
---|
20 | are alphanumeric. |
---|
21 | |
---|
22 | <<iswalnum_l>> is like <<iswalnum>> 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 | <<iswalnum>>, <<iswalnum_l>> return non-zero if <[c]> is a alphanumeric |
---|
28 | wide character. |
---|
29 | |
---|
30 | PORTABILITY |
---|
31 | <<iswalnum>> is C99. |
---|
32 | <<iswalnum_l>> is POSIX-1.2008. |
---|
33 | |
---|
34 | No supporting OS subroutines are required. |
