Start an asynchronous receive on a connected socket.
template< typename MutableBufferSequence, typename ReadHandler = DEFAULT> DEDUCED async_receive( const MutableBufferSequence & buffers, socket_base::message_flags flags, ReadHandler && handler = DEFAULT);
This function is used to asynchronously receive data from the raw socket. The function call always returns immediately.
One or more buffers into which the data will be received. 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.
Flags specifying how the receive call is to be made.
The handler to be called when the receive 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 received. );
Regardless of whether the asynchronous operation completes immediately
or not, the handler will not be invoked from within this function.
On immediate completion, invocation of the handler will be performed
in a manner equivalent to using
The async_receive operation can only be used with a connected socket. Use the async_receive_from function to receive data on an unconnected raw socket.
