The wcsrchr() function shall locate the last occurrence of wc
in the wide-character string pointed to by
ws. The application shall ensure that the value of wc
is a character representable as a type wchar_t and a
wide-character code corresponding to a valid character in the current
locale. The terminating null wide-character code shall be
considered to be part of the wide-character string.
Upon successful completion, wcsrchr() shall return a pointer
to the wide-character code or a null pointer if wc
does not occur in the wide-character string.
No errors are defined.
