Writing to a TCP socket synchronously
Writing to a TCP socket is an output operation that is used to send data to the remote application connected to this socket. Synchronous writing is the simplest way to send the data using a socket provided by Boost.Asio. The methods and functions that perform synchronous writing to the socket block the thread of execution and do not return until the data (at least some amount of data) is written to the socket or an error occurs.
In this recipe, we will see how to write data to a TCP socket synchronously.
How to do it…
The most basic way to write to the socket provided by the Boost.Asio library is to use the write_some() method of the asio::ip::tcp::socket class. Here is the declaration of one of the method's overloads:
template< typename ConstBufferSequence> std::size_t write_some( const ConstBufferSequence & buffers);
This method accepts an object that represents a composite buffer as an argument, and as its name suggests, writes some...
