Standard C Library Functions                           wctype(3C)



NAME
     wctype - define character class

SYNOPSIS
     #include 

     wctypet wctype(const char *charclass);


DESCRIPTION
     The wctype() function is defined for valid  character  class
     names  as  defined in the current locale. The charclass is a
     string identifying  a  generic  character  class  for  which
     codeset-specific type information is required. The following
     character class names are defined in all locales:



     alnum                alpha                 blank
     cntrl                digit                 graph
     lower                print                 punct
     space                upper                 xdigit



     Additional character  class  names  defined  in  the  locale
     definition file (category LCTYPE) can also be specified.


     The function returns a value of type wctypet, which can  be
     used   as   the  second  argument  to  subsequent  calls  of
     iswctype(3C). wctype() determines values of wctypet accord-
     ing to the rules of the coded character set defined by char-
     acter type information in  the  program's  locale  (category
     LCTYPE). The values returned by wctype() are valid until a
     call to setlocale(3C) that modifies the category LCTYPE.

RETURN VALUES
     The wctype() function returns 0 if the given character class
     name   is   not  valid  for  the  current  locale  (category
     LCTYPE); otherwise it returns an object of  type  wctypet
     that can be used in calls to iswctype().
