相当于dup2(sfd, fd) 使 fd 指向sfd所指向的问价描述符(套接字),当close(fd)时,该文件描述符未关闭,而是用shutdown(fd, SHUT_RDWR)则彻底关闭了该文件描述符。 shutdown不考虑描述符的引用计数,直接关闭描述符。也可选择中止一个方向的连接,只中止读或只中止写。 注意: 1)如果有多个进程共享一个套接字...

SHUT_RDWR(2): 关闭sockfd的读写功能。相当于调用shutdown两次:首先是以SHUT_RD,然后以SHUT_WR。 使用close中止一个连接,但它只是减少描述符的引用计数,并不直接关闭连接,只有当描述符的引用计数为0时才关闭连接。 相当于dup2(sfd, fd) 使 fd 指向sfd所指向的问价描述符(套接字),当close(fd)时,该文件描...
