PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (con-
       sult the corresponding Linux manual page for details of Linux behavior), or the  interface  may  not  be  implemented  on
       Linux.

NAME
       wcsrchr - wide-character string scanning operation

SYNOPSIS
       #include <wchar.h>

       wchar_t *wcsrchr(const wchar_t *ws, wchar_t wc);


DESCRIPTION
       The wcsrchr() function shall locate the last occurrence of wc in the wide-character string pointed to by ws. The applica-
       tion shall ensure that the value of wc is a character representable as a type wchar_t and a  wide-character  code  corre-
       sponding  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.

RETURN VALUE
       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.

ERRORS
       No errors are defined.
