TOWUPPER(3)                                         Linux Programmer's Manual                                        TOWUPPER(3)



NAME
       towupper - convert a wide character to uppercase

SYNOPSIS
       #include <wctype.h>

       wint_t towupper(wint_t wc);

DESCRIPTION
       The  towupper()  function  is the wide-character equivalent of the toupper(3) function.  If wc is a wide character, it is
       converted to uppercase.  Characters which do not have case are returned unchanged.  If wc is WEOF, WEOF is returned.

RETURN VALUE
       The towupper() function returns the uppercase equivalent of wc, or WEOF if wc is WEOF.

CONFORMING TO
       C99.

NOTES
       The behavior of towupper() depends on the LC_CTYPE category of the current locale.

       This function is not very appropriate for dealing with Unicode characters,  because  Unicode  knows  about  three  cases:
       upper, lower and title case.

SEE ALSO
       iswupper(3), towctrans(3), towlower(3)
