SYNOPSIS
|
|
#include <wctype.h>
|
|
int iswctype(wint_t <[c]>, wctype_t <[desc]>);
|
|
|
|
#include <wctype.h>
|
|
int iswctype_l(wint_t <[c]>, wctype_t <[desc]>, locale_t <[locale]>);
|
|
|
|
DESCRIPTION
|
|
<<iswctype>> is a function which classifies wide-character values using the
|
|
wide-character test specified by <[desc]>.
|
|
|
|
<<iswctype_l>> is like <<iswctype>> but performs the check based on the
|
|
locale specified by the locale object locale. If <[locale]> is
|
|
LC_GLOBAL_LOCALE or not a valid locale object, the behaviour is undefined.
|
|
|
|
RETURNS
|
|
<<iswctype>>, <<iswctype_l>> return non-zero if and only if <[c]> matches
|
|
the test specified by <[desc]>. If <[desc]> is unknown, zero is returned.
|
|
|
|
PORTABILITY
|
|
<<iswctype>> is C99.
|
|
<<iswctype_l>> is POSIX-1.2008.
|
|
|
|
No supporting OS subroutines are required.
