basic_syncbuf::sync
(C++20)
Non-member functions
 
protected:
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()
