std::basic_osyncstream<CharT,Traits,Allocator>::operator= - cppreference.com (original) (raw)

Move-assigns a synchronized output stream:

Move-assigns the wrapped std::basic_syncbuf from the corresponding member of other (after this move-assignment, other.get_wrapped() returns a null pointer and destruction of other produces no output; any pending buffered output will be emitted) and move-assigns the base std::basic_ostream (this swaps all stream state variables except for rdbuf between *this and other)

[edit] Parameters

other - another synchronized output stream to move from

[edit] Return value

*this
