       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.

NAME

       wcsrchr — wide-character string scanning operation

SYNOPSIS

       #include <wchar.h>

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

DESCRIPTION

       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.1‐2008 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.

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.
