std::basic_...tream::emit(3) C++ Standard Libary std::basic_...tream::emit(3) NAME std::basic_osyncstream::emit - std::basic_osyncstream::emit Synopsis void emit(); Emits all buffered output and executes any pending flushes, by calling emit() on the underlying std::basic_syncbuf. Parameters (none) Example // Run this code #include <iostream> #include <syncstream> int main() { { std::osyncstream bout(std::cout); bout << "Hello," << '\n'; // no flush bout.emit(); // characters transferred; cout not flushed bout << "World!" << std::endl; // flush noted; cout not flushed bout.emit(); // characters transferred; cout flushed bout << "Greetings." << '\n'; // no flush } // destructor calls emit(): characters transferred; cout not flushed // emit can be used for local exception-handling on the wrapped stream std::osyncstream bout(std::cout); bout << "Hello, " << "World!" << '\n'; try { bout.emit(); } catch (...) { // handle exceptions } } Output: Hello, World! Greetings. Hello, World!
