ISWCTYPE(3)						     Linux Programmer's Manual						       ISWCTYPE(3)

NAME

       iswctype - wide-character classification

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), 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() function.

RETURN VALUE

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

CONFORMING TO

       C99.

NOTES

       The behavior of iswctype() depends on the LC_CTYPE category of the current locale.

NAME

       wctype - wide-character classification

SYNOPSIS

       #include <wctype.h>

       wctype_t wctype(const char *name);

DESCRIPTION

       The  wctype_t type represents a property which a wide character may or may not have.  In other words, it represents a class of wide charac-
       ters.  This type's nature is implementation-dependent, but the special value (wctype_t) 0 denotes an invalid  property.	 Nonzero  wctype_t
       values can be passed to the iswctype(3) function to actually test whether a given wide character has the property.

       The  wctype()  function	returns  a  property,  given  by its name.  The set of valid names depends on the LC_CTYPE category of the current
       locale, but the following names are valid in all locales.
	 "alnum" - realizes the isalnum(3) classification function
	 "alpha" - realizes the isalpha(3) classification function
	 "blank" - realizes the isblank(3) classification function
	 "cntrl" - realizes the iscntrl(3) classification function
	 "digit" - realizes the isdigit(3) classification function
	 "graph" - realizes the isgraph(3) classification function
	 "lower" - realizes the islower(3) classification function
	 "print" - realizes the isprint(3) classification function
	 "punct" - realizes the ispunct(3) classification function
	 "space" - realizes the isspace(3) classification function
	 "upper" - realizes the isupper(3) classification function
	 "xdigit" - realizes the isxdigit(3) classification function

RETURN VALUE

       The wctype() function returns a property descriptor if the name is valid.  Otherwise it returns (wctype_t) 0.

CONFORMING TO

       C99.

NOTES

       The behavior of wctype() depends on the LC_CTYPE category of the current locale.
