NAME
       wcsstr - locate a substring in a wide-character string

SYNOPSIS
       #include <wchar.h>

       wchar_t *wcsstr(const wchar_t *haystack, const wchar_t *needle);

DESCRIPTION
       The  wcsstr function is the wide-character equivalent of the strstr function. It searches for the first occur-
       rence of the wide-character string needle (without its terminating L'\0' character)  as	a  substring  in  the
       wide-character string haystack.

RETURN VALUE
       The wcsstr function returns a pointer to the first occurrence of needle in haystack. It returns NULL if needle
       does not occur as a substring in haystack.

       Note the special case: If needle is the empty wide-character string,  the  return  value  is  always  haystack
       itself.
