Socket option for the send buffer size of a socket.

typedef implementation_defined send_buffer_size;

Implements the SOL_SOCKET/SO_SNDBUF socket option.

Examples

Setting the option:

std::experimental::net::ip::tcp::socket socket(io_context);
...
std::experimental::net::socket_base::send_buffer_size option(8192);
socket.set_option(option);

Getting the current option value:

std::experimental::net::ip::tcp::socket socket(io_context);
...
std::experimental::net::socket_base::send_buffer_size option;
socket.get_option(option);
int size = option.value();
