std::basic_syncbuf::emit(3) C++ Standard Libary std::basic_syncbuf::emit(3) NAME std::basic_syncbuf::emit - std::basic_syncbuf::emit Synopsis bool emit(); Atomically transmits all pending output to the wrapped stream. All emit() calls transferring characters to the same wrapped stream buffer object appear to execute in a total order, where each emit() call synchro- nizes-with subsequent emit() calls in that total order, even if these calls are made through difference instances of std::basic_syncbuf/std::basic_osyncstream. In practice, this means that emit() takes a lock uniquely associated with the wrapped stream object: for example, it could be held in a static hash map where the address of the wrapped stream is used as the key. If a call had been made to sync since the last call to emit(), then also flushes the wrapped stream by calling pubsync() on it. Parameters (none) Return value true if all of the following is true: * there is a wrapped stream (the wrapped streambuf pointer is not null) * all characters from the temporary storage were successfully sent into the wrapped stream * the call to pubsync(), if requested, also completed success- fully. Returns false otherwise. Notes Normally called by the destructor of the owning std::basic_osync- stream or by std::basic_osyncstream::emit.
