:
int sync ( ) override ; |
||
First, records that a flush is pending, by updating the appropriate private flag.
Then, if the current emit-on-sync policy is true , makes a call to emit() .
Otherwise (if the emit-on-sync policy is false , which is the default), the flush is suspended until emit() is called, such as through std::basic_osyncstream::emit() or std::basic_osyncstream::~basic_osyncstream
Parameters
(none)
Notes
sync()
or its equivalent is implicitly called by
close()
,
seekoff()
, and
seekpos()
and explicitly called by
std::basic_streambuf::pubsync()
