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
       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
       ISO/ANSI C, UNIX98

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

NOTES
       The behaviour 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.
