NAME

6       wcsstr - locate a substring in a wide-character string
7

SYNOPSIS

9       #include <wchar.h>
10
11       wchar_t *wcsstr(const wchar_t *haystack, const wchar_t *needle);
12

DESCRIPTION

14       The wcsstr() function is the wide-character equivalent of the strstr(3)
15       function.  It searches for the first occurrence of  the  wide-character
16       string  needle (without its terminating null wide character (L'\0')) as
17       a substring in the wide-character string haystack.
18

RETURN VALUE

20       The wcsstr() function returns a pointer to the first occurrence of nee‐
21       dle  in  haystack.   It returns NULL if needle does not occur as a sub‐
22       string in haystack.
23
24       Note the special case: If needle is the  empty  wide-character  string,
25       the return value is always haystack itself.
