std::basic_syncbuf<CharT,Traits,Allocator>::sync - cppreference.com

From cppreference.com

protected:intsync()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()

Example

See also

[virtual]

synchronizes the buffers with the associated character sequence
(virtual protected member function of std::basic_streambuf<CharT,Traits>)

[edit]

calls

emit()

on the underlying basic_syncbuf to transmit its internal data to the final destination
(public member function of std::basic_osyncstream<CharT,Traits,Allocator>)
