basic_timeout_socket::async_write_some

Start an asynchronous write.

Synopsis

template<
    class ConstBufferSequence,
    class WriteHandler>
DEDUCED
async_write_some(
    ConstBufferSequence const& buffers,
    WriteHandler&& handler);

Description

This function is used to asynchronously write data to the stream socket. The function call always returns immediately.

Name	Description
`buffers`	One or more data buffers to be written to the socket. Although the buffers object may be copied as necessary, ownership of the underlying memory blocks is retained by the caller, which must guarantee that they remain valid until the handler is called.
`handler`	The handler to be called when the write operation completes. Copies will be made of the handler as required. The 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. ); Regardless of whether the asynchronous operation completes immediately or not, the handler will not be invoked from within this function. Invocation of the handler will be performed in a manner equivalent to using boost::asio::io_context::post().

handler

The handler to be called when the write operation completes. Copies will be made of the handler as required. The 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.
);

Regardless of whether the asynchronous operation completes immediately or not, the handler will not be invoked from within this function. Invocation of the handler will be performed in a manner equivalent to using boost::asio::io_context::post().
