WMEMCHR(3P)                POSIX Programmer's Manual               WMEMCHR(3P)
PROLOG
       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
       wmemchr -- find a wide character in memory
SYNOPSIS
       #include <wchar.h>
       wchar_t *wmemchr(const wchar_t *ws, wchar_t wc, size_t n);
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  wmemchr()  function shall locate the first occurrence of wc in the
       initial n wide characters of the object pointed to by ws.   This  func-
       tion  shall  not  be affected by locale and all wchar_t values shall be
       treated identically. The null wide character  and  wchar_t  values  not
       corresponding to valid characters shall not be treated specially.
       If  n  is zero, the application shall ensure that ws is a valid pointer
       and the function behaves as if no valid occurrence of wc is found.
RETURN VALUE
       The wmemchr() function shall return a pointer to the located wide char-
       acter,  or  a  null pointer if the wide character does not occur in the
       object.
