Shutdown of a socket, to know how to end. Thank you Shutdown of a socket, to know how to end. SIGPIPE signal Shutdown of a socket, to know how to end. My understanding is the key to how you shutdown, which is on the side of the operation, what if 1, shutdown (sockfd, SHUT_RD), end-to-end connection at this time is to send the data, then he would return SIGPIPE signal at this time is to end recv so, not knowing there were already a shutdown 2, shutdown (sockfd, SHUT_WR), the terminal is send data at this time, then it can not imagine that if correct will be received in recv recv FIN and then return 0 3, shutdown (sockfd, SHUT_RDWR) or send recv whether in the end we know that recv return 0 send signals received SIGPIPE These views are purely personal opinion, if wrong, hope you enlighten ~~~~~ :) [ Closed window ]
