• 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.
  Non-zero 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.
