wchar_t* wcsstr( const wchar_t* dest, const wchar_t* src ); | (since C95) |
Finds the first occurrence of the wide string src in the wide string pointed to by dest. The terminating null characters are not compared.
| dest | - | pointer to the null-terminated wide string to examine |
| src | - | pointer to the null-terminated wide string to search for |
Pointer to the first character of the found substring in dest, or a null pointer if no such substring is found. If src points to an empty string, dest is returned.

Строка, где есть подстрока 'но'.
