asio :: tcp :: socket的async_read_some和async_receive有什么区别？ [英] What is the difference between asio::tcp::socket's async_read_some and async_receive?

问题描述

之间有什么区别：

• boost :: asio :: tcp :: socket :: async_read_some （）


• boost :: asio :: tcp :: socket :: async_receive（） li>
  

我可以告诉他们的文档是相同的。

他们在 sc22 / wg21 / docs / papers / 2006 / n2054.pdf>网络TR2提议（5.7.10.2 basic_stream_socket成员）也是相同的：

在async_receive ：

效果：调用this-> service.async_receive（this-> implementation，buffers，0，handler）。

打开async_read_some：

.async_receive（this-> implementation，buffers，0，handler）。

所以我想这证实了Jerry的印象。

What is the difference between:

• boost::asio::tcp::socket::async_read_some()
• boost::asio::tcp::socket::async_receive()

As far as I can tell their documentation is identical.

Which should I prefer?

解决方案

Their specification in the networking TR2 proposal (5.7.10.2 basic_stream_socket members) is identical too:

On async_receive:

Effects: Calls this->service.async_receive(this->implementation, buffers, 0, handler).

On async_read_some:

Effects: Calls this->service.async_receive(this->implementation, buffers, 0, handler).

So I guess this confirms Jerry's impression.
