iswctype(3) Library Functions Manual iswctype(3)
iswctype - wide-character classification
Standard C library (libc, -lc)
#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), then 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
attributes(7).
