Equivalent to return rdbuf()->view();. Parameters (none) Return value A std::basic_string_view over the underlying string object. Example // Run this code #include <iostream> #include <sstream> int main() { // input/output stream std::stringstream buf1; buf1 << 69; int n = 0; buf1 >> n; std::cout << "1) buf1 = [" << buf1.view() << "], n = " << n << '\n'; // output stream in append mode std::ostringstream buf2("test", std::ios_base::ate); buf2 << '1'; std::cout << "2) buf2 = [" << buf2.view() << "]\n"; // input stream std::istringstream inbuf("-42"); inbuf >> n; std::cout << "3) inbuf = [" << inbuf.view() << "], n = " << n << '\n'; } Output: 1) buf1 = [69], n = 69 2) buf2 = [test1] 3) inbuf = [-42], n = -42 See also view obtains a view over the underlying character sequence (C++20) (public member function of std::basic_string- buf<CharT,Traits,Allocator>) http://cppreference.com 2024.06.10 std::basic_...stream::view(3)
