PROLOG

NAME

12       wcsrchr — wide-character string scanning operation
13

SYNOPSIS

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

DESCRIPTION

20       The functionality described on this reference page is aligned with  the
21       ISO C  standard.  Any  conflict between the requirements described here
22       and the ISO C standard is unintentional. This  volume  of  POSIX.1‐2017
23       defers to the ISO C standard.
24
25       The  wcsrchr()  function  shall locate the last occurrence of wc in the
26       wide-character string pointed to by ws.  The application  shall  ensure
27       that the value of wc is a character representable as a type wchar_t and
28       a wide-character code corresponding to a valid character in the current
29       locale. The terminating null wide-character code shall be considered to
30       be part of the wide-character string.
31

RETURN VALUE

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