问题描述

read()和recv()有什么区别，send()和write() 在套接字编程中的性能、速度和其他行为?

What is the difference between read() and recv(), and between send() and write() in socket programming in terms of performances, speed and other behaviors?

推荐答案

不同的是recv()/send()只对socket描述符起作用，让你为实际操作指定某些选项.这些函数更专业一些(例如，您可以设置一个标志来忽略 SIGPIPE，或者发送带外消息...).

The difference is that recv()/send() work only on socket descriptors and let you specify certain options for the actual operation. Those functions are slightly more specialized (for instance, you can set a flag to ignore SIGPIPE, or to send out-of-band messages...).

函数read()/write()是通用文件描述符函数，作用于所有描述符.

Functions read()/write() are the universal file descriptor functions working on all descriptors.
