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 wmemchr() function shall locate the first occurrence of wc  in  the
       initial n wide characters of the object pointed to by ws. This function
       shall not be affected by locale and all wchar_t values shall be treated
       identically. The null wide character and wchar_t values not correspond-
       ing 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.
