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 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.
