对于BSD,是AF,对于POSIX是PF UNIX系统支持AF_INET,AF_UNIX,AF_NS等,而DOS,Windows中仅支持AF_INET,它是网际网区域. 在函数socketpair与socket的domain参数中有AF_UNIX,AF_LOCAL,AF_INET,PF_UNIX,PF_LOCAL,PF_INET.这几个参数有AF_UNIX=AF_LOCAL,PF_UNIX=PF_LOCAL,AF_LOCAL=PF_LOCAL,AF_INET=PF_INET....

SOCK_STREAM提供面向连接的稳定数据传输，即TCP协议。SOCK_STREAM应用在C语言socket编程中，在进行网络连接前，需要用socket函数向系统申请一个通信端口。socket函数的使用方法如下：int socket(int domain, int type, int protocol);在参数表中，domain指定使用何种的地址类型，比较常用的有：PF_INET, AF_...
