towupper — convert a wide character to uppercase
#include <wctype.h>
wint_t towupper( |
wint_t | wc) ; |
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.
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.
iswupper(3), towctrans(3), towlower(3)
