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 characters.  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() function to actu-
       ally 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() classification function
         "alpha" - realizes the isalpha() classification function
         "blank" - realizes the isblank() classification function
         "cntrl" - realizes the iscntrl() classification function
         "digit" - realizes the isdigit() classification function
         "graph" - realizes the isgraph() classification function
         "lower" - realizes the islower() classification function
         "print" - realizes the isprint() classification function
         "punct" - realizes the ispunct() classification function
         "space" - realizes the isspace() classification function
         "upper" - realizes the isupper() classification function
         "xdigit" - realizes the isxdigit() 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.
