|
* @par Examples
|
||
|
|
* Setting the option:
|

|
|
* @code
|

|
|
* asio::ip::tcp::socket socket(io_service);
|
||
|
|
* ...

|
* socket.set_option(option);
|
||
|
|
* @endcode
|
||
|
|
*
|
||
|
|
* @par
|
||
|
|
* Getting the current option value:
|
||
|
|
* @code
|
||
|
|
* asio::ip::tcp::socket socket(io_service);
|
||
|
|
* ...
|
