template< class ConstBufferSequence, class WriteHandler> DEDUCED async_write_some( ConstBufferSequence const& buffers, BOOST_ASIO_MOVE_ARG(WriteHandler) handler);
This function is used to asynchronously write one or more bytes of data to the stream. The function call always returns immediately.

Description |
---|---|
|
The data to be written to the stream. Although the buffers object may be copied as necessary, ownership of the underlying buffers is retained by the caller, which must guarantee that they remain valid until the handler is called. |
|
The handler to be called when the write operation completes. Copies will be made of the handler as required. The equivalent function signature of the handler must be: void handler( const boost::system::error_code& error, // Result of operation. std::size_t bytes_transferred // Number of bytes written. ); |
The async_write_some
operation
may not transmit all of the data to the peer. Consider using the boost::asio::async_write
function if you need to ensure
that all data is written before the asynchronous operation completes.
