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

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  val‐
       ues  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 cur‐
       rent locale.
