std::wcsstr(3) C++ Standard Libary std::wcsstr(3) NAME std::wcsstr - std::wcsstr Synopsis Defined in header <cwchar> 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. Parameters dest - pointer to the null-terminated wide string to examine src - pointer to the null-terminated wide string to search for 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. Example // Run this code #include <iostream> #include <cwchar> #include <clocale> int main() { wchar_t const* origin = L", , , , , ."; wchar_t const* target = L""; 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; ++re- sult) std::wcout << L"Found: \"" << result << L"\"\n"; } Possible output: Substring to find: "" String to search: ", , , , , ." Found: ", , , , ." Found: ", ."
