NAME
     towupper - transliterate lower-case wide-character  code  to
     upper-case

SYNOPSIS
     #include 

     wint_t towupper(wint_t wc);


DESCRIPTION
     The towupper() function has as a domain a type  wint_t,  the
     value  of  which  must  be  a  character  representable as a
     wchar_t, and must be  a wide-character code corresponding to
     a  valid  character  in  the  current locale or the value of
     WEOF. If the argument has any other value, the  argument  is
     returned unchanged. If the argument of towupper() represents
     a lower-case wide-character code (as  defined  by  character
     type  information  in the program locale category LC_CTYPE),
     the result is the  corresponding  upper-case  wide-character
     code.  All  other  arguments  in  the  domain  are  returned
     unchanged.

RETURN VALUES
     Upon successful completion, towupper()  returns  the  upper-
     case letter corresponding to the argument passed. Otherwise,
     it returns the argument unchanged.

ERRORS
     No errors are defined.
