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



 

NAME


       towupper - convert a wide character to uppercase

 

SYNOPSIS


       #include 

       wint_t towupper(wint_t wc);

 

DESCRIPTION






       The  towupper()  function is the wide-character equivalent of the toup-
       per(3) function.  If wc is a wide character, it is converted to  upper-
       case.  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 cur-
       rent locale.

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