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 terminat­
       ing L'\0' character) as a substring in the  wide-character
       string haystack.


RETURN VALUE

       The  wcsstr function returns a pointer to the first occur­
       rence 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-charac­
       ter string, the return value is always haystack itself.
