Socket representation.
It is not thread-safe to concurrently read from socket. It is not thread-safe to concurrently write to socket. However it is safe to concurrently read and write into socket:
for (char expected_data = 0; expected_data <= 100; ++expected_data) {
char c = 0;
EXPECT_EQ(1, recvfrom.bytes_received);
EXPECT_EQ(expected_data, c);
}
});
for (char send_data = 0; send_data <= 100; ++send_data) {
const auto bytes_sent = socket.
SendAllTo(addr, &send_data, 1, deadline);
EXPECT_EQ(bytes_sent, 1);
}
read_task.Get();
