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



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 char-
       acter may or may not have. In other words, it represents a
       class of wide characters.  This type's nature is implemen-
       tation  dependent,  but  the  special  value   (wctype_t)0
       denotes  an  invalid property. Nonzero wctype_t values can
       be passed  to  the  iswctype  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 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.

NOTES
       The  behaviour  of wctype depends on the LC_CTYPE category
       of the current locale.
