wcsrchr - search a wide character in a wide-character string
wchar_t *wcsrchr(const wchar_t *wcs, wchar_t wc);
The wcsrchr() function is the wide-character equivalent of the str
rchr(3) function. It searches the last occurrence of wc in the wide-
character string pointed to by wcs.
The wcsrchr() function returns a pointer to the last occurrence of wc
in the wide-character string pointed to by wcs, or NULL if wc does not
occur in the string.
