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 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 character, or a null pointer if the
       wide character does not occur in the object.
