wctype.h(3HEAD)                     Headers                    wctype.h(3HEAD)



NAME
       wctype.h, wctype - wide-character classification and mapping utilities

SYNOPSIS
       #include <wctype.h>

DESCRIPTION
       The <wctype.h> header defines the following types:

       wint_t       As described in <wchar.h>.


       wctrans_t    A  scalar type that can hold values that represent locale-
                    specific character mappings.


       wctype_t     As described in <wchar.h>.



       The <wctype.h> header defines the following macro name:

       WEOF    Constant expression of type wint_t that is returned by  several
               MSE functions to indicate end-of-file.



       For  all  functions described in this header that accept an argument of
       type wint_t, the value is representable as a wchar  _t  or  equals  the
       value  of  WEOF.  If this argument has any other value, the behavior is
       undefined.


       The behavior of these functions is affected by the LC_CTYPE category of
       the current locale.


       Inclusion  of  the  <wctype.h> header can make visible all symbols from
       the headers <ctype.h>, <stdarg.h>, <stddef.h>,  <stdio.h>,  <stdlib.h>,
       <string.h>, <time.h>, and <wchar.h>.
