<tbody> </tbody> basic_ostream& flush(); |
||
Writes uncommitted changes to the underlying output sequence.
If rdbuf() is a null pointer, does nothing
Otherwise, constructs a sentry object which checks the stream for errors and flushes the tie()'d output streams. If the sentry object returns false, does nothing (seit C++11)
Otherwise, calls rdbuf()->pubsync(). If the call returns -1, calls setstate(badbit).

Beispiel
#include <thread>
#include <iostream>
#include <chrono>
void f()
{
std::cout << "Output from thread...";
std::this_thread::sleep_for(std::chrono::seconds(2));
std::cout << "...thread calls flush()\n";
std::cout.flush();
}
int main()
{
std::thread t1(f);
std::this_thread::sleep_for(std::chrono::seconds(1));
std::clog << "Output from main\n";
t1.join();
}
Output:
Output from main
Output from thread.....thread calls flush()
