wcsstr(3)

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(3)
   function.  It searches for the first occurrence of  the  wide-character
   string  needle (without its terminating null wide character (L'\0')) 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.
