iswctype — wide-character classification
#include <wctype.h>
int
iswctype( |
wint_t | wc, |
wctype_t | desc) ; |
If wc
is a wide
character having the character property designated by
desc
(or in other
words: belongs to the character class designated by
desc
), the
iswctype
() function returns
non-zero. Otherwise it returns zero. If wc
is WEOF, zero is
returned.
desc
must be a
character property descriptor returned by the wctype
function.
The iswctype
() function
returns non-zero if the wc
has the designated property.
Otherwise it returns 0.
