I just realized that I pasted too many lines. The presence of the "hints" variable in the code above became misleading. It is important to point out that the error does not happen if I pass the hints to getaddrinfo, like this: struct addrinfo hints; struct addrinfo *addi; ::memset(&hints, 0, sizeof(hints)); hints.ai_family = AF_UNSPEC; hints.ai_socktype = SOCK_STREAM; hints.ai_protocol = IPPROTO_TCP; int status = ::getaddrinfo(hostname, "9999", &hints, &addi); I'm intrigued about the different behaviors of Linux and Android when the hint parameter is NULL. Which one is correct? -- My preferred quotation of Robert Louis Stevenson is "You cannot make an omelette without breaking eggs". Not because I like the omelettes, but because I like the sound of eggs being broken. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "android-framework" group.
