Имя (Name)

wcsstr - locate a substring in a wide-character string

---

Синопсис (Synopsis)

#include <wchar.h>

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

---

Описание (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.

---

Возвращаемое значение (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.
