No, I have not been calling getaddrinfo directly. This is a production software which is executed at a customer site, and it's rare that the problem occur. > you never know that it may be the library which is slowing things down. I'm not sure what library you're referring to here (asio or the winsock library). SUSEConnect error: SocketError: getaddrinfo: Name or Mar 03, 2020 Newest 'getaddrinfo' Questions - Server Fault getaddrinfo(3) failed I'm trying to connect to a webservice using a PHP wrapper (which is using curl under the covers).

還有，你會在這裡看到 AI_PASSIVE 旗標；這個會告訴 getaddrinfo() 要將我本機的位址（address of local host）指定給 socket structure。這樣很棒，因為你就不用把位址寫死了[或者你可以將特定的位址放在 getaddrinfo() 的第一個參數中，我現在寫 NULL 的那個參數]。

The getaddrinfo() function combines the functionality provided by the gethostbyname(3) and getservbyname(3) functions into a single interface, but unlike the latter functions, getaddrinfo() is reentrant and allows programs to eliminate IPv4-versus-IPv6 dependencies. The addrinfo structure used by getaddrinfo() contains the following fields: Dec 22, 2015 · The buffer overflow occurs in the functions send_dg (send datagram) and send_vc (send TCP) for the NSS module libnss_dns.so.2 when calling getaddrinfo with AF_UNSPEC family, or in some cases AF_INET6 family. The use of AF_UNSPEC (or AF_INET6 in some cases) triggers the low-level resolver code to send out two parallel queries for A and AAAA. Jul 01, 2020 · If it’s red it means the variable is unresolved so, generally, either they’d include an environment for you to import ( which doesn’t seem to be the case here ) or expect you to define a variable, in this case, host, with the appropriate domain or host for the API. Microsoft's man page equivalent says "The getaddrinfo function provides protocol-independent translation from an ANSI host name to an address.", which appears also ti indicate that it expects to be handed a host name rather than a dotted-quad string. If the host at 10.2.41.11 has a host name, try using it instead of the dotted-quad.
