std::basic_...tream::view(3)   C++ Standard Libary  std::basic_...tream::view(3)

NAME
     std::basic_istringstream::view - std::basic_istringstream::view

Synopsis
	std::basic_string_view<CharT,  Traits>	view()	const  noexcept;  (since
     C++20)

	Obtains a std::basic_string_view  over	the  underlying  string  object.
     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
