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 occurrence 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.
