 boost::asio::buffer_cast<>()是你应该用来访问缓冲区使用的指针。 boost::asio::buffer_size()是你应该用来访问所用大小的东西。 
 
 例如 
 
const std::string test("test");
const size_t len = std::min(boost::asio::buffer_size(mybuf), test.length());
memcpy(boost::asio::buffer_cast<void *>(mybuf),
    test.c_str(),
    len);
const std::string test2("test");
boost::asio::mutable_buffer offset = mybuf + len;
const size_t len2 = std::min(boost::asio::buffer_size(offset), test2.length());
memcpy(boost::asio::buffer_cast<void *>(offset),
    test.c_str(),
    len2);

boost::asio::mutable_buffer offset2 = offset + len2;

boost::asio::buffer_cast<>() is what you should use to get access to the pointer used by the buffer. boost::asio::buffer_size() is what you should use to get access to the size used.
 
e.g.
 
const std::string test("test");
const size_t len = std::min(boost::asio::buffer_size(mybuf), test.length());
memcpy(boost::asio::buffer_cast<void *>(mybuf),
    test.c_str(),
    len);
const std::string test2("test");
boost::asio::mutable_buffer offset = mybuf + len;
const size_t len2 = std::min(boost::asio::buffer_size(offset), test2.length());
memcpy(boost::asio::buffer_cast<void *>(offset),
    test.c_str(),
    len2);

boost::asio::mutable_buffer offset2 = offset + len2;
