| Defined in header | | | | -------------------------------------------------------------------------- | | | | const wchar_t* wcsstr( const wchar_t* dest, const wchar_t* src ); | | | | wchar_t* wcsstr( wchar_t* dest, const wchar_t* src ); | | |

Finds the first occurrence of the wide string src in the wide string pointed to by dest. The terminating null characters are not compared.

[edit] Parameters

[edit] Return value

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.

[edit] Example

#include #include #include   int main() { wchar_t const* origin = L"アルファ, ベータ, ガンマ, アルファ, ベータ, ガンマ."; wchar_t const* target = L"ベータ"; wchar_t const* result = origin;   std::setlocale(LC_ALL, "en_US.utf8"); std::wcout << L"Substring to find: "" << target << L""\n" << L"String to search: "" << origin << L""\n\n";   for (; (result = std::wcsstr(result, target)) != nullptr; ++result) std::wcout << L"Found: "" << result << L""\n"; }

Possible output:

Substring to find: "ベータ" String to search: "アルファ, ベータ, ガンマ, アルファ, ベータ, ガンマ."   Found: "ベータ, ガンマ, アルファ, ベータ, ガンマ." Found: "ベータ, ガンマ."
