Data may be read from or written to a
connected TCP socket using the
receive(),async_receive(),send() or
async_send() member functions.
However,as these could result in
short writes or reads,an application
will typically use the following
operations instead: read(),
async_read(),write() and
async_write().

我真的不明白这句话因为read(),async_read(),write()和async_write()也可能以短写或读取结束,对吧？
为什么这些功能不一样？
我应该使用它们吗？
有人可以为我澄清这句话吗？
