NAME¶

std::basic_ostringstream::view - std::basic_ostringstream::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
