wcsstr - find a wide-character substring
#include <wchar.h>
wchar_t *wcsstr(const wchar_t *restrict ws1, const wchar_t *restrict ws2);
ISO C++
#include <wchar.h>
const wchar_t *wcsstr(const wchar_t *ws1, const wchar_t *ws2);
#include <cwchar>
wchar_t *std::wcsstr(wchar_t *ws1, const wchar_t *ws2);
The wcsstr() function locates the first occurrence in the wide-
character string pointed to by ws1 of the sequence of wide-
characters (excluding the terminating null wide-character) in the
wide-character string pointed to by ws2.
On successful completion, wcsstr() returns a pointer to the located
wide-character string, or a null pointer if the wide-character string
is not found.
If ws2 points to a wide-character string with zero length, the
function returns ws1.
No errors are defined.
