[edit] Example
Run this code
#include <iostream> #include <strstream> int main() { std::strstream dyn; // dynamically-allocated output buffer dyn << "Test: " << 1.23 << std::ends ; std::cout << "The size of the output is " << dyn.pcount() << " and it holds \"" << dyn.str() << "\"\n"; dyn.freeze(false); char buf[10]; std::strstream user(buf, 10); // user-provided output buffer user << 1.23; // note: no std::ends std::cout.write(buf, user.pcount()); std::cout << '\n'; }
Output:
The size of the output is 11 and it holds "Test: 1.23" 1.23
