       The  functionality  described  on  this  reference  page is aligned with the ISO C standard. Any conflict
       between the requirements described  here  and  the  ISO C  standard  is  unintentional.  This  volume  of
       POSIX.1‐2017 defers to the ISO C standard.

       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.

       No errors are defined.

       wcsrchr — wide-character string scanning operation

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

       None.

       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.
