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 nonzero. Otherwise, it
returns zero. If
wc is
WEOF, zero is returned.
desc must be a character property descriptor returned by the
wctype(3) function.
The
iswctype() function returns nonzero if the
wc has the
designated property. Otherwise, it returns 0.
For an explanation of the terms used in this section, see
