NAME

13       wcsrchr — wide-character string scanning operation
14

SYNOPSIS

16       #include <wchar.h>
17
18       wchar_t *wcsrchr(const wchar_t *ws, wchar_t wc);
19

DESCRIPTION

21       The functionality described on this reference page is aligned with  the
22       ISO C  standard.  Any  conflict between the requirements described here
23       and the ISO C standard is unintentional. This  volume  of  POSIX.1‐2008
24       defers to the ISO C standard.
25
26       The  wcsrchr()  function  shall locate the last occurrence of wc in the
27       wide-character string pointed to by ws.  The application  shall  ensure
28       that the value of wc is a character representable as a type wchar_t and
29       a wide-character code corresponding to a valid character in the current
30       locale. The terminating null wide-character code shall be considered to
31       be part of the wide-character string.
32

RETURN VALUE

34       Upon successful completion, wcsrchr() shall return  a  pointer  to  the
35       wide-character code or a null pointer if wc does not occur in the wide-
36       character string.
