iswctype(3)             Library Functions Manual             iswctype(3)

NAME

       iswctype - wide-character classification

LIBRARY

       Standard C library (libc, -lc)

SYNOPSIS

       #include <wctype.h>

       int iswctype(wint_t wc, wctype_t desc);

DESCRIPTION

       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.

RETURN VALUE

       The iswctype() function returns nonzero if the wc has the
       designated property.  Otherwise, it returns 0.
