### iswctype -- Test for Character Property

Format

>     #include <wctype.h>
>     int iswctype(wint_t wc, wctype_t wc_prop);

Language Level: ANSI 93, XPG4
iswctype determines whether the wide character wc has the property wc_prop. It is similar in function to the iswalnum through isxdigit functions, but with iswctype you can specify the property to check for, or check for a property other than the standard ones.

You must obtain the wc_prop value from a call to wctype. If you do not, or if the LC_CTYPE category of the locale was modified after you called wctype, the behavior of iswctype is undefined.

The value of wc must be representable as an unsigned wchar_t, or WEOF.

The following strings correspond to the standard (basic) character classes or properties:

"alnum" | "cntrl" | "lower" | "space"
"alpha" | "digit" | "print" | "upper"
"blank" | "graph" | "punct" | "xdigit"

Return Value
iswctype returns a nonzero value if the wide character has the property tested for. If the value for wc or wc_prop is not valid, the behavior is undefined.

Example

isalnum to isxdigit -- Test Integer Value
isascii -- Test Integer Values
isblank -- Test for Blank Character Classification
_iscsym - _iscsymf -- Test Integer
iswblank -- Test for Wide Blank Character Classification
iswalnum to iswxdigit -- Test Wide Integer Value
