| 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 (desde C++11)
Otherwise, calls rdbuf()->pubsync(). If the call returns -1, calls setstate(badbit).
