SYNOPSIS

9       #include <wctype.h>

DESCRIPTION

15       The  towupper()  function  has  as a domain a type wint_t, the value of
16       which the application shall ensure is a character  representable  as  a
17       wchar_t,  and  a wide-character code corresponding to a valid character
18       in the current locale or the value of WEOF. If  the  argument  has  any
19       other  value,  the behavior is undefined. If the argument of towupper()
20       represents a lowercase wide-character code, and there exists  a  corre‐
21       sponding  uppercase  wide-character  code (as defined by character type
22       information in the program locale category LC_CTYPE ), the result shall
23       be  the  corresponding  uppercase wide-character code.  All other argu‐
24       ments in the domain are returned unchanged.
25

RETURN VALUE

27       Upon successful completion, towupper() shall return the uppercase  let‐
28       ter  corresponding  to  the argument passed. Otherwise, it shall return
29       the argument unchanged.
