First, records that a flush is pending, by updating the appropriate private flag.
Then, if the current emit-on-sync policy istrue, makes a call toemit().
Otherwise (if the emit-on-sync policy isfalse, which is the default), the flush is suspended untilemit() is called, such as throughstd::basic_osyncstream::emit() orstd::basic_osyncstream::~basic_osyncstream
