Shadowsocks Getpeername Invalid Argument
them; it only takes a minute: Sign up C++ connect function error - Invalid argument up vote 1 down vote favorite I'm trying to make a simple socket client (using debian 6 and g++ compiler) and when I'm calling "connect" struct sockaddr function, it returns error code 22 - Invalid argument. Tell me, what am I doing wrong, please. I've read the man page for this function and it says that the 3 arguments must be as followed: int, struct sockaddr* and socklen_t. My code is: int serverPort; u_long serverHost; struct sockaddr_in serverAddress; socklen_t serverAddressLength; int clientSocket; serverPort = 44444; serverHost = inet_addr ( "88.198.237.65" ); serverAddress.sin_family = AF_INET; serverAddress.sin_port = htons ( serverPort ); serverAddress.sin_addr.s_addr = htons ( serverHost ); socklen_t serverAddressLength = sizeof ( serverAddress ); clientSocket = socket ( AF_INET , SOCK_STREAM , 0 ); connect ( clientSocket , (sockaddr*)&serverAddress , serverAddressLength ) c++ sockets arguments connect share|improve this question edited Aug 3 '12 at 14:22 asked Aug 3 '12 at 14:08 Kolyunya 2,29121947 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote accepted serverAddress.sin_addr.s_addr = htons ( serverHost ); An IPv4 address is a long, not a short, so htons is right out. The data is in network byte order already anyway, so no conversion is needed. The inet_addr() function converts the Internet host address cp from IPv4 numbers-and-dots notation into binary data in network byte order. Also: char serverHost; How's it supposed to fit in a char? share|improve this answer answered Aug 3 '12 at 14:11 David Schwartz 108k899163 wrt to your final question - Luck?! –Ed Heal Aug 3 '12 at 14:17 Thank a lot, David! May i ask you, why if I don't apply htons to serverHost on the server side, bind function returns "Cannot assign requested address" and returns "Socket binded successfully" if I DO use htons? Thanks a lot again! –Kolyunya Aug 3 '12 at 14:30 @Kolyunya: Don't try to understand known buggy code. It will just make you crazy. (Probably, by luck, the htons turned it into a zero, which is probably what you really wante
